The HWND variables are destroyed when you return from the callback procedure..
Due to which when next time the procedure called it declares the HWND variables and WM_INITDIALOG message fire only once..
solution for this is make the variables as static/global.

Thanks a lot for your help, it actually works now. Declaring the handles as static actually fixed the darn thing. I never realized the callback procedure kills the handles everytime its returned but I can see why that problem was occuring. Im just glad we were able to fix it and now I can move on to bigger and better things.
I will include my code for future reference for anyone searching for a tab control example in C++ because I was never able to find an example like this anywhere on the net.

Maybe you should combine SW_SHOWDEFAULT for current sub-dialog with SW_HIDE for the rest ones, for instance:
ShowWindow(tab1_hwnd, SW_SHOWDEFAULT);
ShowWindow(tab2_hwnd, SW_HIDE);

Can you mention it more clearly what you have to do.....If it is login checking and showing the respective dialog then it's more easy and you should fight on it...

You should be checking the text of the boxes with the entries in the columns of the table say login(table). set a flag variable for the admin/user type.
Based on this flag value you can show the dialogs you wish to show.
Somethings seem HARD to do, until we know how to do them.

The people in this forum have been answering your question for quite a while now.
Anyways this is hint :
Extract the date from the string.
From this string extract yyyy,mm and dd.
Now using CString::Format() again format the date and insert it into the datetime picker.
Somethings seem HARD to do, until we know how to do them.

You just have to modify 2006-05-05 date which you fetched from the MYSQL database
CString strTestDate("2006-05-05");<br />
or strTestDate=Fetcheddate;<br />
and System Time is taken for synchronisation of the date which is already explained in the post.
Hope you got the solution now.

If the date is returning from mysql is in different format then ou have to eplcitly reformat it....
and if not then you can change the format of date in MySql database.

Hello,
Can anyone tell me how to specify the file name to open using PostMessage,
The code:
PostMessage(hwnd,WM_COMMAND,(WPARAM)ID_FILE_OPEN,NULL), works fine but still I have to specify the file name.
Note: the window i posted the message is another application window, this is what I asked for!
PostMessage(hwnd=Other app main frame window, ...)
Kind regards.

If your intention is to open a known file in an MFC application without prompting the user, I think you can try this:
AfxGetApp()->OpenDocumentFile("file path");

As u have to debug my program,i use breakpoint in my program,after i press f5 to start debugging,but an error dialog is came like that "One or more breakpoints cannot be set abd have been disabled.Execution will stop at the beginning of the program"
And the breakpoint get disabled and i could not debug the program.
How can i do this?
Pls..
|

It seems like you have a Release configuration active. Setting the Current Configuration to Debug should help.
this is this.
|
|
|
|

Check if your program is compiled under debug mode and contains debug information (you have to check that in the project properties which are specific to the IDE you are using). Check also that the breakpoint is on a valid line (a line that produces assembler code). For example, putting a breakpoint on a variable declaration won't work (as it doesn't produce any assembler instruction).
