    Thanks. I think this one works better and a faster response time (searches/lookup etc): One of those files, a .zip of the HTML Help, has been uploaded to this repository.

    Because I don't know what version the code snips are until later on in reading the entire discussion. These are google search results. I see a snippet and read what's going on. I try it and see if it works on my main laptop computer which has XE7. And if it doesn't work either I'll keep reading further or try it on Delphi 11.2 or 12.2 as those are the three versions I have. But not all google-found search results include the versions of Indy in those discussions. I am just searching google for info and if code snippets are given I try them out for fun or interest. Not all say the version of Indy, and if I can't find any further info to resolve any issues that I might run into while trying those snippets then I might post a question here on Praxis, or not, and move on. Delphi is my hobby. Sometimes I get *new* ideas from these random google searches and they become hobby projects. In fact, I just started a new project from this as of yesterday, a Client/Server app and it appears to be working okay. First time I ever accomplished this as I always wanted to get a client/server (send/receive text) project working via Indy but failed many times. But not this time. But is it perfect or correct? Probably not. But it works. :) I was meaning to post a few questions because I had many issues, about 18 or more hours worth (I just could not stop). I'm stuck on an issue or two and still working them out. Maybe I'll post a question or two later, if I can't figure it out as it is driving me nuts. Also, I have searched around on all my versions of Delphi (xe7, 11.2 and 12.2) and did not see any documentation or Samples folder for Indy. And the link in the About of the Indy components (when you rightl-click the component in the IDE) do not work on any of those Delphi versions.

    Scroll an image with mouse (Solved)

    JohnLM posted a topic in VCL

    I am having trouble figuring this one out. I have a form with a tscrollbox and an timage. In the image1MouseMove event of the timage I have the following code; procedure TForm2.im1MouseMove(Sender: TObject; Shift: TShiftState; X, Y: Integer); begin scrollbox1.vertScrollBar.Position := x; scrollbox1.horzScrollBar.Position := y; end; But it is not what I'd expect. What I am trying to do: 1. Lets say I have screenshot of my desktop and inserted into the timage. 2. And I resize the app's form smaller 3. Using the mouse, I want to click on the image and drag (or pan) around inside the form's scrollbox area so that I can see other parts of the image. What am I doing wrong and how can I fix this? TIA

    Thank you @Lajos Juhász for your suggestion. I had tried a few mods late last night but I could not get it to work any better. And thank you @Anders Melander for your suggestion. It is working the way I was hoping. And, I learned a little bit about Delta. Thank you both for your help, it is appreciated!

    Specs: Win10, Delphi 12.2 - Installing fresh because previous 12.2 installation did not include Android support. 2nd fresh install, same issue. I've reinstalled 12.2 but have no android support and when I plug the usb cable in, there is no device -- field is blank. Okay, so for sure, I thought I would not have this issue this time around in this latest release, but disappointed that this continues every new version install. What can I do? Please advise.

    Update. . . Success and Resolved. Thank you @Z Vadim for the solution. In order to work, I had to search for the "sdkmanager.bat" file and found here: C:\Users\Public\Documents\Embarcadero\Studio\23.0\CatalogRepository\AndroidSDK-2525-23.0.53571.9782\cmdline-tools\11.0\bin\sdkmanager.bat I closed down Delphi 12.2, and made sure I was connected to the internet, and went to that folder and ran the following: sdkmanager.bat "platform-tools" "platforms;android-34" I now have moble development working for Android for the first time in the 12.2 version.

    Specs: win10 tablet I am unable to install 12.2 It removed 12.0 but the installation stops at: Platforms availability No more platforms pending to install. Any suggestions?
  8. JohnLM
    At the start of the installation is a [Options] button for changing folder locations. And I was trying to install to another drive instead of the standard C: drive. It did not like it, I guess. When I changed it to the default location, the installation went ahead, successfully, about 50 minutes.

    Just reporting 12.2 has successfully installed.

    Issue is resolved and installation is now continuing.

    Because I have a small, 128GB hdd in my tablet, I want to install on an external SSD drive. What are the pros and cons for installing on another drive?

    License Specs: Delphi 11.2 Alexandria 11/2022 I finally and recently purchased a 1-yr 'support renewal', which ends nov/2024 so that I could get the 12.2 version. However, I have not received any email confirmation with the new license/serials, and I don't see any updates to my https://my.embarcadero.com/ account. It is the same listing since 11/2022. And when I tried to download the 12.2 iso it said that my update subscription expired and to request a renewal quote. The one I recently purchased was this one: "Delphi Professional - Named - Support Renewal" But I do see there are others mentioned here on these forums: * maintenance update -- * update subscription - - * support renewal -- the one I purchased. Did I purchase the wrong one?

    Current Specs: Delphi XE7, vcl, win7 and MD5 checksum decoding Update. . . on other news.. regarding the MD5 checksum number given at the download page. I spent hours trying to find out how to do MD5 encode/decode, and finally found the answer I was looking for. I found this routine that worked in XE7 at least, but not tested for other versions old or newer. When run and fed the filename, it took several minutes to process and complete. Happy to say that the checksum produced from the routine below matched the website's !! I hope this code-snippet below, becomes useful for other users. ///// 5a // link; https://stackoverflow.com/questions/447985/file-md5-checksum 9.13.24.fri.0614pm // function MD5File(const FileName: string): string; var IdMD5: TIdHashMessageDigest5; FS: TFileStream; begin IdMD5 := TIdHashMessageDigest5.Create; FS := TFileStream.Create(FileName, fmOpenRead or fmShareDenyWrite); try Result := IdMD5.HashStreamAsHex(FS) finally FS.Free; IdMD5.Free; end; end; ///// - end 5a -- this compiles successfully. procedure TForm1.Button1Click(Sender: TObject); var hash: string; begin // 5a -- "F:\Delphi\Embarcadero\RADStudio_12_2_9782_9961F.iso" hash := md5file(edit1.Text); edit1.Text := hash; end;

    Update. . . Success! I made contact with my sales rep and I am now able to download the 12.2 iso.

    Specs: Delphi XE7, 11 and 12, VCL, Win7/10 I work mainly on my win7 latop. And there is this file that I check for stats purpsoes every day and throughout the day as I am working on the laptop. And in one instance today, it dawned on me that I need to know if I was connected to the internet or not. Plus, a side bonus could be helpful to know that if I lose internet I could do something about it. In win7 I noticed that in the bottom task tray area, there is the icon, the one with the square monitor looking image (sure its different in win10), when I hover the mouse over it or click on it, it will say, "Internet access" Is there some delphi code-snippet already out there that will tell me that I am connected to the internet, like in the above mentioned?

    Specs: Delphi XE7, FMX, Win7, Win10, - Creating an App Tethering app for each platform (windows/android/tablet/laptop) I've had my share of problems in this app tethering endeavor but over-come most, if not all of them. In this latest issue I appear to have found a slight bug in the differences between Delphi XE7 and Delphi 12 (and I'm sure in previous version as well). Let me explain. 1. I have several demo app tethering that I created in Delphi XE7 for a windows 7 laptop and android 12 phone, and they work fine. I can send/receive text. 2. I have also create demo apps for app tethering in Delphi 11.2/12.0 for a windows 10 tablet and laptop, and they work fine. I can send/receive text. 3. The problem arrises when I create the same project in XE7, and using the same setup I would in the other app tethering (Password, Resource->Kind=value, Resource->Name=text, ResType=data) but that the send and receive app(s) do not find each other. So, the XE7 app tether cannot find that D11 or D12 app tethering and vise-versa. I need to create certain apps under XE7 for my daily windows 7 laptop because this is my main working computer. My other win10 tablet and laptop(s) are my secondary work devices. My question is, is there a work-around for this?
  17. JohnLM
    Update. . . I can confirm that the above issue is true. Creating the 'app tether' send/recieve app: 1. If I create the apps on my main laptop using Delphi XE7 and the same ones on another device with Delphi 12.0, and then run both apps, they will not connect. But I found a work-around. 2. If I create the apps in Delphi XE7, and copy all the apps to all machines, laptops, and devices, then they will all connect.

    Specs: Delphi XE7, FMX, Win7, Galaxy s10+ phone Android 12. I've have compile and deployed many apps over to my Android 12 device, galaxy s10+ phone. Earlier this year (2024) I stopped working on those projects I used to compile in this setup/specs (listed above). Today, I am trying to deploy an app and now I can not because of the 'Unsafe app blocked message'. I recall seeing something similar in late Dec/2023 on this phone, but there was a button to allow or not, and now I don't see that on this message screen given on my phone. How can I resolve this?

    JohnLM replied to JohnLM's topic in Cross-platform

    Success!! Okay. I figured out what was causing the problem. I need new glasses. I could not see the part about the link and clicked "Got it" which does not install. 1. So, I deleted the Android folder from the project folder. 2. Then, I restored a backup copy of the origianl unaltered "AndroidManifest.template.xml" file. 3. Compiled/deployed to android. 4. when a "Unsafe app blocked' message appears on the android phone, just above the large blue "Got it" button, click the "More details" link. 5. when you see additional details display, click on the "Install anyway" link. 6. enter your phones sign-on password 7. a dialog of security questions will appear, I just click the Continue button, bottom right. 8. another dialog box pops up for "look for updates.." and "ok". select OK button. 9. app will now load up. -- finished

    I started a new FMX project for android. I only added an edit box. I did not change the template xml file. I left it alone. Then I build it, and that was a success. Then, I compiled/deployed to android. Result: same issue as in post #8 above. I just don't understand it. This was working fine before, back in Dec/2023. And now I can't even compile a small editbox over to android. So frustrating. 😞

    post #8 I believe I am doing things correctly now. However, it is not working yet. See below for the XML file that I modified for Delphi XE7, and where I replaced the var android:targetSdkVersion="%targetSdkVersion%" with android:targetSdkVersion="31". <?xml version="1.0" encoding="utf-8"?> <!-- BEGIN_INCLUDE(manifest) --> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="%package%" android:versionCode="%versionCode%" android:versionName="%versionName%"> <!-- This is the platform API where NativeActivity was introduced. --> <uses-sdk android:minSdkVersion="%minSdkVersion%" android:targetSdkVersion="31" /> <%uses-permission%> <application android:persistent="%persistent%" android:restoreAnyVersion="%restoreAnyVersion%" android:label="%label%" android:installLocation="%installLocation%" android:debuggable="%debuggable%" android:largeHeap="%largeHeap%" android:icon="%icon%" android:theme="%theme%" android:hardwareAccelerated="%hardwareAccelerated%"> <!-- Our activity is a subclass of the built-in NativeActivity framework class.

    I've edited the "AndroidManifest.template.xml" file and changed the value in the %targetSdkVersion% field from 11 to 31 but when I re-build it (not deploy it), it is changed back to the default of 11. I did notice that there are several copies of the "AndroidManifest.xml" file in the Android folder of the project folder, and I have made the same changes, from 11 to 31. But the value reverts back to 11. I must be updating the wrong file somewhere. Are there steps that show how to excactly make the necessary changes where and when, etc. ?

    JohnLM replied to JohnLM's topic in Cross-platform

    Yes, this one. . . I get that above message and then it closes on its own, and the app (this time) does not get installed. In previous deploying to my android 12 device, it would install but I would get a message similiar to above (not exact) but with the option to allow or uninstall--if memory serves me correctly.

    I am successfully app tethering from a delphi 12.0 win10 tablet to a delphi 11.2 win10 laptop over wifi through a small portable mini wifi hotspot. (The device is a mini router hotspot with internet. However, the 'internet' service was cancelled years ago, but the wifi router portion works fine and I can connect via app tethering with this device successfully and without the worry of being hacked over internet since there is no internet on this device.) Also, I have successfully app tethered with these two (win10 tablet and laptop) in the past over the wifi when I had a working wifi/bluetooth chip in the win7 laptop. However, that chip no longer works so no wifi and no internet on the win7 laptop. But, to get around this, I have discovered that I can get internet on it if I connect my cellphone to it through usb and set my phone to 'app tether'. And this has been and still is working for me for the last 6 months. This past week or so, I decided I need to start transferring some files and other things over from the win7 laptop to my other devices via app tethering but I am failing with the software connecting to the win7 laptop. The way I have the win10 tablet and win10 laptop and win7 laptop to the mini wifi router: 1. In each device, I set the wifi to point to the mini wifi hotspot router. 2. finished And, the way I have the win10 table and win10 laptop and win7 laptop software setup is as follows: 1. D12 win10 tablet as the server -- tpro (Shared) 2. d11.2 win10 laptop as the client -- tpro (Mirror) 3. xe7 win7 laptop as the client -- tpro (Mirror) When I run all three software and begin with the win10 tablet as the server, it finds and connects with the win10 laptop, but not with the win7 laptop. And I can pass text over to the win10 laptop. I believe the issue has something to do with using the proper IP address on the cellphone and/or on the laptop or, I have to set things up so that it reads the cellphones IP addres and then the laptops IP addres in order to connect. But since I know nothing about networking, I am clueless how to get this part working for the win7 laptop over usb to cellphone for app tethering. Does anyone here know how I can configure these two software for the server part (win10 tablet), and the win7 laptop ? (I will be sending text and files from the win7 laptop, so I will have that as the server too.)
