    debugging crash

    I did have a crash when setting 64-bit debug to release on d11.1. And some wrecks running 10.4 in same time frame when switching over. To fix that mess I switched to 32 bit and hit compile all projects and also may have overwritten a .dproj or two by starting up with .dpr to get fresh dproj. I plan inspect the dcus freshness next time! 32==>64 is OK but 64==>32 may not have worked well on 10.4. On 11 64 debug ==> 64 release the custom components in Palette were dimmed when unable to load.

    Lost Code Format Menu option....

    Try using the finder(s) first type format in Title bar finder finds Options under tools then type formatter in options title bar.

    debugging crash

    First set a break point or hit F7 or F8 before running F9 that either key should run to cursor last position. It may be keys are remapped to Alt - F4 somehow.

    Loading data from dfm

    I suspect the root cause is one needs to override the virtual method with override then the inherited can be commented out or moved as needed.

    Tstringgrid grid index out of bounds

    Couple of things that might help with the port is That coding would yield where the cursor or record pointer is if a flat file? Renaming Field Name 'c' to align to what stored in it. Then Colcount would renamed to align to whats begin returned. I suspect its layout number. There is a columns count or fields count plus records count for each table. I think that older codebase should considered in final trim. Any improvements don't touch vintage code. If you're using 10.x program the improvements to suit that vintage. Over time d5 vintage code is not used very much. Good luck comes from months of careful planning and testing of enlightened repairs or good maintenance. Making a procedure in the DataModule that populates the VCL Control passed to it that can used any form that uses DMxx; the DMxx would only need VCL.grids added to the uses clause not needing the form calling it adding to uses clause. DM Public procedure getDataforSG(aCDS, aCDS2: TClientDataSet; rangeLeft, rangeRight, rangeTop, rangeBottom: Integer; aFieldName: string; //... aSG: TStringGRid); ... implementation procedure TDM.getDataforSG(aCDS, aCDS2: TClientDataSet; rangeLeft, rangeRight, rangeTop, rangeBottom: Integer; aFieldName: string; aSG: TStringGRid); var I,J: integer; RackID: Integer; TubIDcol: Integer;//Variant; csvfieldNames: string; fishName: string; begin aSG.Rows[0].CommaText := 'row'+ aFieldName; if rangeRight > CDS.FieldCount then rangeRight := CDS.FieldCount; if rangeBottom > CDS.RecordCount then rangeBottom:= CDS.recordCount; aSG.ColCount := rangeRight-rangeLeft; aSG.RowCount := -rangeBottom-rangeTop; //To find what c is about //pass in aFieldName := 'c'; for I := rangeTop to rangeBottom do begin aCDS.RecNo := I; fishName := ACDS.FieldByName(aFieldName).AsString; ASG.Rows[I].CommaText := aFieldName + ',' + fishName; end; //build SL header for I := rangeLeft to rangeRight do begin csvfieldNames := csvfieldNames + CDS.Fields[I].Name + ',' end; ASG.Rows[0].CommaText := ('Row,' + csvfieldNames); //Put your tubCDS code here Insert into form procedure Tmain.buildrackClick(Sender: TObject); const MagicNumberUp = 1; MagicNumberDown = -1;// would need inserted to adjust SG row offset var c, r, box : Integer; RackId : string; begin //ShowMessage('draw grid'); //setgridrow := -1; //setgridcol := -1; //box := 0; //RackId := ListBox1.Items[ListBox1.ItemIndex]; RackId := 'c'; getDataforSG(ffdata,tubdata,0 +MagicNumberUp,50000,0+MagicNumberUp,50000,RackID,StringGrid1); //(** comment rest out for now **)
  7. You missed the name of program interSector.dir It calls the chips intersector routine look at the disassembly. The only documentation I have found is this. VP2INTERSECT I done a lot of spreadsheets using just formulas over the years... Excel Range("A1:A10").Select 'Selects cells A1 to A10. Range(Range("A1"), Range("A10")).Select 'Selects cells A1 to A10. Range("A1, A10").Select 'Selects cells A1 and A10. Union(Range("A1"), Range("A10")).Select 'Selects cells A1 and A10. Range("A1:A5 A5:A10").Select 'Selects cell A5. Intersect(Range("A1:A5"), Range("A5:A10")).Select 'Selects cell A5. Delphi's DB and graphics have similar functions. TList<T> has range! Pat

    INI problem

    Consider MemInifile.setStrings(SL) I use it for Demos. Using it seems to reduce waking the Antimal. const Brand = 'PF'; const wrappedBrand = '\'+Brand+'\'; var IniNotFound: Boolean; var BrandNotfound: BooLean; var iniDir := Tpath.GetPublicPath; var AppHappyName := Application.Title; //following yielded /appdata/Roaming //PathedIniFile := System.SysUtils.GetHomePath + Application.Title + '.Ini'; var PathedIniFileName := iniDir + wrappedBrand + AppHappyName + '.Ini'; IniNotFound := not fileexists(PathedIniFileName); BrandNotfound := not DirectoryExists(iniDir + '\' + Brand); if BrandNotfound then ForceDirectories(iniDir + '\' + Brand); InidataFile := Tmeminifile.Create(PathedIniFileName); if IniNotFound then begin var SL: TStringList; SL := TStringList.Create; try SL.Text := cDefaultIni; IniDataFile.SetStrings(SL); IniDataFile.UpdateFile; // comment out for Demo finally SL.Free; end; end;

    Incompatible types bug in D11.1

    How to name Consider numerous Excel users that do not name the ranges. Naming allows the formulas to be readable and robust. In excel a name could refer to the cell that a spin control is assigned to. In Delphi the default naming scheme reflects what control or control property we are using. Knowing what slows down many XL users, one could change the arguments passed to fit the names of what is wanted or needed. procedure TfrmViewMain.MoveShapeItem(Value: TPanel; AStepDelay: Integer = 100); //Value should only used inside a TComponent in Property.setter IMHO //reflect name of thing wanted. procedure TfrmViewMain.MoveShapeItem(Panel: TPanel; AStepDelay: Integer = 100); // a good start procedure TfrmViewMain.MoveShapeItem(MovetoRight, LeftFence: TControl; AStepDelay: Integer = 100); //or may be a little much procedure TfrmViewMain.MoveShapeItem(var MovetoRight.Left, LeftFence.Left:Integer; AStepDelay: Integer = 100); //for intent use Control-J summary template to roll your poppy. //for errors look at left view mirroe in Structure

    Dynamic creation of TActionManager with Actions

    Use ActionManager as in design window and its property editors and sub editors adding stubs to be used like this to connect the events at runtime. procedure TForm1.Button2Click(Sender: TObject); const popupmenuitemCaptions: array[0..1] of String=('Action4','frameAction1'); var popupFrameCaption: string; I: Integer; A: TContainedAction; begin for popupFrameCaption in popupmenuitemCaptions do for I := 0 to ActionManager1.ActionCount - 1 do begin A := ActionManager1.Actions[I]; if A.caption = popupFrameCaption then begin A.OnExecute := Frame11.PopupActionBar1.Items[0].OnClick; A.Execute; Break; end; end; end; object ActionManager1: TActionManager ActionBars = < item Items.CaptionOptions = coAll Items = <> ActionBar = ActionToolBar3 end> LinkedActionLists = < item Caption = '(No Name)' end> Images = ImageList1 Left = 722 Top = 172 StyleName = 'Platform Default' object Action4: TAction Category = 'Frame' Caption = 'Action4' ImageIndex = 1 OnExecute = Action4Execute end object DatasetFirst1: TDataSetFirst Category = 'Dataset' Caption = '&First' Hint = 'First' ImageIndex = 0 end end Inspecting the object in design by copying it to notepad shows Images property to possibly set at runtime.

    Window /client size bug in 10.4

    Actually Marco's post is between D11 to D10.4 PE flags updated to 6 to allow thinner borders and more margin. Try Autosizing False and Center True. To center image on form set align = alClient. That allows changing images readily.

    Window /client size bug in 10.4

    If you stored the image in the image control. Try this in 10.4 Select Image in Design window. Bring up the Picture editor F11 for object inspector and click on ellipses ... In the Picture editor save image as some thing else plus extension what it was.( .bmp .ping) view the image with other app. Other wise just delete the image control and install fresh one.

  20. That means to a painter read the directions on can One gallon to 100 square feet. To a pilot ground school. To a programmer a little knowledge is a dangerous thing--drink deep or drink not*. I try make a game of it, reading a chapter out of a book, write some code in notepad, and if runs without error I win big and even a few errors is a win when the coding structure is remembered readily. That how I sharpened my axe in the olden days now I use notepad++ 🙂 *A quote quoted in Pascal with Excellence.

    Get memory used by a Memtable record??

  22. Replace with magic overloaded procedure the compiler knows which to use with args passed. procedure serverExecute(AThread: TIdContext; const aFileName); overload; ... procedure TForm1.serverExecute(AThread: TIdContext; const aFileName); Add second overloaded procedure. Never Merge when better to unravel!

    auto fill parameters

    You are saying local variable names are prefixed with 'a' when your function is used? That lets the person reading the code know what variables are to be touched outside the procedure. That's better than marking the variables that are not touched outside a procedure with an L. I think the Help insight control J s for summary is good. It has better latency than the Control Space business.

    auto fill parameters

    Wouldn't a custom template do? Hitting CreateC shown with Control-J yields constructor Create(AOwner: TComponent); override;

    mouse move on screen

    Just put the image you are using for the desktop into your program. double click on the form in the IDE to bring up FormCreate. set backgroundImage named imgAnimals with pix used for desktop image. You can use Panels for rendering your Boxes that have labels allready centered! imgAnimals := Timage.Create(Self) parent := Self; imgAnimals.align := alClient; imgAnimals.Picture.LoadFromFile(cAnimalPixPathed); (**above put this stuff. const cAnimalPixPathed = 'path and filename'; var imganimals: TImage; //Put upstairs BoxLabels := TList<TPanel> **); {You move the panels in BoxLabels around with mouse then use show and hide as necessary.}
