So, the thicken plots.... I have narrowed it down to using the ''' construct with the ExpandedText property of a TTaskDialog. I create the TTaskDialog in code. Everything is happy with this: ExpandedText := '1. Wait - The App will try to reconnect until it connects or it has another connection timeout.' + sLineBreak + '2. Cancel - This is a last resort selection and will result in an Application crash and generate a formal error report.' + sLineBreak + 'At this error prompt you have the normal error report options.' + sLineBreak + 'If you don?t know or understand the error report dialog or the options available you should ask to your Workflow System Administrator.' + sLineBreak + 'It is strongly recommended that you select these options in the following priority/order => Wait then Cancel.'; As soon as I put all the text into the ''' construct and double click on the OnShow property of the form, It gives me the error that it can't find OnShow. Interestingly, I didn't get the 'finally-end' inserted as I edited the text.

Hi Brian, You may have hit on something there. I think I first noticed it when I was setting up text within the ''' - ''' multi-line structure. The 4 files I found the issue in had been so edited. I restored previous versions of each and all was fine. Today I was just editing one of those files in the IDE and was in the process of restructuring a block of text per the ''' multi-line structure, when it happened. 😞 I had pressed enter at the end of the text line and got a 'finally-end' back. 😞 I did a test again to see if double clicking on the OnShow Event would work, and no, it now failed per my original experience. I tried to back out the ''' construct, but the issue persisted. 😞 I restored a 1 hour old backup and it was fine. Note to Self: Don't bother with ''' constructs for the foreseeable future. This isn't a Patch 1 specific issue, 3 of the 4 files restored went 'faulty' around mid-Jan & the fourth around mid-Dec. Unfortunately, I can't replicate this in a test App. 😞 Ian

Hi Team, For what ever reason, it doesn't happen anymore. I didn't take notes, but I'm wondering if it was somehow related to the other issue I posted about which has been resolved. Seemingly corruption of some sort that I couldn't identify. Unfortunately, I can't recall if I experienced this issue in those Projects specifically, or in others. 😞 Certainly the issue reproduceable and annoying. Everything is working as expected now. Thank you all for your contributions. I will keep my fingers crossed... Regards, Ian

D12 + Patch. I just double clicked on the FormShow event of a Form to create the event. I got a "Cannot find implementation of method FormShow.: error. I checked, the declaration is in the Form Class and the procedure is in the code. Huh?? I added some code into the FormShow procedure but it doesn't run. I don't get any error messages. Any thoughts/suggestions?? Regards, Ian

😞

I backtracked through the versions and found that three developed the issue in mid January and one in mid Dec. Doing the usual file comparisons, I couldn't find a change/difference in the sour dfm files. 😞 All restored now and working as desired. Thanks for looking. Ian

Update - I just went through the 30 projects in the ProjectGrp. 4 projects are exhibiting the issue. 😞 I guess that narrows it down to what do those 4 have in common....

Hi Dave, No it didn't happen on a new project. And it isn't happening on/in all my projects in the proj Gp. But it is happening in more than one. 😞 I can't really post the form/project as it has 3rd Pary components on it and there is proprietary information in it. Whilst I could mask the information, it would still be dependant on you having the 3rd Party components to open the unit. What's a little more annoying is that I don't know how long this 'isssue' has existed and therefore how long existing FormShow procedures in the relevant Apps hasn't been functioning. 😞 Ian

My KSVC update seemingly installed OK but when I went to update my project it couldn't find some KSVC components. I had to de/re install KSVC and all was good. Does anybody know what the KSVC update changed/updated? Regards, Ian

Hi Team, D12. What would/could prevent me being able to widen my MainForm? There are no Constraints and the form is sizable. It is a Normal form. I can change the height OK, but not the width. 😞 Any thoughts/suggestions appreciated. Regards & TIA, Ian

Found it! One of the components on the form ahd constraints for some reason. All fixed now. Thanks to all for your input. Regards, Ian

Hi Brian, I could be wrong, this is not in code, this is in the IDE at Design time. Ian

Hi Team, Books have been written about what I don't know about threading... 😉 I have experimented with Anonympus threads. Is it possible to prevent the App doing anything except being moved, and parhas resized, while a thread is running? Regards & TIA, Ian

Because I still want them to be able to move and resize the App/Form while the thread is running. If I do it in the main thread the form becomes unresponsive.

Well done to Uwe, Peter, & any others, for seeing this issue through. Ian

Hi Team, Like most of us I have my own local pattern procedure/function library. I have been commenting them like this: What this gives me then is a dropdown when I hover over the procedure/finction in my code that looks something like this: All very handy and a useful reminder of the procedure/function definition. I forget where I got this from. 😞 Can somebody point me to where this style of documentation/technique is documented please? Regards & TIA, Ian

They don't appear to have a D12 version yet. 😞

Excellent! Thanks Dalija. Regards, Ian

Of course, all of this is dictated by available Budget and/or Risk/Impact analysis.

Here's a thought. What impact, if any, has this outage had on the next update to D12??

Hi Team, Delphi 12. I am trying my hand at Semaphores. Never touched them before this. ATT I have the following code: // // Create the named semaphore (if it doesn't already exist) GlobalSemaphore := TSemaphore.Create(nil, 1, 1, 'DBiAdminSemaphore'); // try // if GlobalSemaphore.Acquire then begin I understand that if the Semaphore 'DBiAdminSemaphore' already exists, it won't be created again. If it already exists, I want to test for its existance, hence the thought of Acquire, but it seems Acquire doesn't return a Boolean. How do I test if the Semaphore already exists? The objective here is to prevent the following code exceuting if the Semaphore exists. Regards & TIA, Ian

Hi Jon, Tks. The code is in the MainForm.FormShow Event. The App is accessed by multiple Users via ThinFinity (WEB), RDP & LAN. If one of the App has the GlobalSemaphore created, I don't want any of the other Apps running this piece of code. I don't know that I need to use Acquire at all? If WaitFor(1) works as suggested, I will be fine. Regards, Ian

Hi Team, I have a table with a blob field that contains jpeg files of approx 256kB size. I want to reduce their size to around 128kB size. Thus reducing the overall table size. Iterating through the table isn't an issue, I need to read the image, reduce its physical size then write it back to the field. Preferably without too much degradation. Thoughts/suggestions appreciated. Regards & TIA, Ian

Hi Guys, FWIW, I am using both without issue in D12. Ian

Getting to be a habit... 😞
