I am a neophyte programmer. I have figured out how to generate a simple Delphi 7 form with a button in it which will run an executable. , , procedure TForm1.Button1Click(Sender: TObject);, begin, ShellExecute(Form1.Handle, 'open', 'c:\E3238s\bin\E3238s.exe',, nil, nil, SW_SHOWNORMAL);, end;, end., , My problem is I need to know how to access the menus that are a part of this executable. For example how would I access the FILE menu in order to select EXIT.

Hello delphiers,, , Im not sure if anyone of you have come across this error message "Class not registered". I get this message when i try to create a COM object which starts communicating with the respective client-side program., , The client-side program in context is Lotus Notes 6.0.3. I have installed it on the same PC where I have Delphi 5 Ent installed, I also have run the notesws.reg file which adds the relevant registry entries. The .tlb files in the \lotus\notes\ directory are also installed in Delphi., , The moment I create the NotesSession object, I get this error message., , Somehow i feel that the classes are not able to find one or more keys or CLSID or GUID written into the registry. I traced through the .Create method to be able to make this guess. The GetSrv or GetServer method fails in the .tlb / OleSys.pas file., , How to go about fixing this problem? Where should i look? What is not yet installed or configured?, , Regards,, , Mani

good day!, can any body please help me on how to transfer files from one computer to another using sockets or what other means., thanks a lot :)

I have recently made a successful use of importing a type library and installing the component produced. This works fine in D7, but I only have the desktop version, and I need to be able to do it in D6 to use database access., , Now in D6, the library is imported and a source file produced which theoretically could be installed as a component. There is an "Install" button on the import dialog. However, the source produced will not compile. The error is "Property setter cannot have var parameters"., , It seems odd that D6 produces source code on the import which the compiler cannot then compile. Does anyone have any experience with this, or know a work-around. My inclination is to add "wrapper" procedures which don't have var parameters., , Neville

I'm new to the COM scene, and don't know how to supply a pointer to the client's IDispatch interface to a COM server. When I don't provide this, the server behaves just fine when I call it, but crashes every time it attempts a callback. , , Below is the function call in question with the only documentation I have :, , function TMapper.RegisterWithMapServer(const client_name: WideString; window_handle: Integer; dispatch_pointer: OleVariant): Integer;, , "RegisterWithMapServer registers the map server client name and main window handle. Map server clients MUST call this function once at start up BEFORE calling any of the other functions. The parameter dispatch_pointer should be of type VT_DISPATCH and should contain a pointer to the client's IDispatch interface for the callback object.", , Thank in advance for ANY help!, , n

I'm programming a form that is fed by an SQL component in a datamodule. I programmatically define the statement with "...add()" statements; ie, , , datamodUSARunitCmdr.sqlAARpt.SQL.clear;, datamodUSARunitCmdr.sqlAARpt.SQL.add('SELECT hdr.aarDate,hdr.aarUnitIdent, hdr.aarSubmitDate, ');, ...., datamodUSARunitCmdr.sqlAARpt.open;, datamodUSARunitCmdr.sqlAARpt.enableControls;, , (I know the SQL-statement returns a recordSet, given the proper values for the parameters)., , The problem is that when the program reaches the "....clear" statement, the following exception is thrown:, "Either EOF or BOF is True, or the current record has been deleted. Requested operation requires a current record"., , What would cause this?, How could it be resolved?, If the query returns a recordSet, how could it generate an exception?

I am using Delphi5, trying to develop small database.When I refresh ADOTable connected to a MS Access database trough ODBC, I get this message: "Project stdatabase.exe raised exception class EOLEException with message "Insufficent key column information for updating or refreshing. Process stoped.Use Step ot Run to continue". There's no matter whether I refresh it programatically or trough database navigator component. What should I do to make it works?

I've modified a component and registered it. Now I've tried to re-register the original version. However upon testing, it just seems to pick the later version. I've even renamed the newer version hoping MTS does not pick it up but the results are always the same. , , Thanks in advance.

i need help! how do i make my program run in the system tray? or how can i hide my program from the task bar?, , thanks :)

I have as many of you will be aware been fighting a losing battle with a COM object I have been trying to import, and utilise. , , I have after much investigation discovered that all the errors I am getting and in the OleServer.pas file on the event called, , TServerEventDispatch.GetTypeInfoCount, , I then get an error code:, , "access violation at 0x0044204d: write address of 0x00000003", , Is this a known bug of OleServer.pas or something to do with my imported COM object. The code for my object is in one of my previous threads. (UnImported CoClass Routines I think), , Hope someone can help as I am at the end of the plank, with a noose round my neck as far as this is concerned. Not Actually however it is getting to be like that., , Thanks in advance
