But 1/10 errors of your code was because of the compiler. but as I said, my program was working, and I got that error. and later, it started working again. I do not think that was my fault. thatnx.

I found what the mistake was myself. thanx anyway. I hope you will answer my future questions. Best Regards exceter.

Greate, it works. thanx. but, how to make it to work with Getbuffer()? well, in this program I know the estimated sizes of the buffer, but if it exceeds the buffer size I've shoen there?

what is your problem with this piece of code? Don't try it, just do it! ;-)

Why would you want to do this? If your ID column is referenced from somewhere else, you will have to update all those tables too. Let the hole be! Especially if you're using IDENTITY. (It can be done, but will be some work, as you first will have to temporarily SET IDENTITY INSERT ON for your table. Insert row 4 in row 3's place, delete row4, insert row 5 in row 4's place. (Which you offcourse will do in a loop.)) If you really really need this functionality, it is better NOT to use the IDENTITY column, since that will allow you to use an UPDATE statement instead. (Possibly in a trigger or a stored proc...)

But if you don't use SELECT * you will get errors in your SQL query and will have one more possibility to think about consequences of column renaming and adapt the client code appropriately. With SELECT * you might forget about adapting the client code. And in many cases you won't even see compile-time errors. If you are just reordering columns, you won't have to change anything.

It was not meant to be "disallowed." See my reply about OnKillActive().

I've done this several times without issue. The only (apparent) difference is that I don't use .NET, but use VS6 instead. Surely .NET can't be that goofy.

Try to create a control member data m_EditBox with the class wizard, and set the text with m_EditBox.SetWindowText(MyStr);. If it is still not updating it, then the display refreshing must hang in another part of your code. (You could also first try a RedrawWindow() after the UpdateData(FALSE)). ~RaGE();

there are some things to consider: 1. if you are trying to use the code as you've shown us... the main problem is that App is not initialized when you want to access it... 2. if you are trying to get access to the main application object, then the declaration is not correct: you should change CStudentApp *App; for extern CStudentApp StudentApp; doing this you'll be accessing the real application object created in OnInitInstance... 3. as the compiler says the try block has no catch... you should catch the exceptions you want to handle... catch(...) for catching all of them. hope this helps...

ok .. can you tell us what is written in the log file.. it may explain the problem.. also what OS do you use ?

:)I guess thats something like this.. virtual void OnDraw(CDC* pdc, const CRect& rcBounds, const CRect& rcInvalid); public: virtual BOOL InitInstance(); i guess that should work fine with your code.. cheers Himanshu

You may also try the easy solution : Add your button in the ressource editor. Doubleclick on it to open properties. Give it a name (for instance ID_OPENFILE). Close the window, go open the class wizard. Select your button name in the list on the right and handle the corresponding message. All the stuff given by Himanshu will be added automatically. Oh, BTW, Himanshu, feel free to put your code into a <pre> environment, it is far more readable. ;P ~RaGE();
