Jignesh putting a picture onto a toolbar button ns23-Jul-02 3:02 ns 23-Jul-02 3:02  I copied the "binoculars" from toools-customize-commands-edit pane with "copy" and want to put this image on my toolbar button. This is just a new button in the standard toolbar IDR_MAINFRAME. How do I do this ? I tried "paste" but it didnt show up at runtime, even though in the resource editor, the image was there in the 16x16 square bitmap of the toolbar button (but not showing in the toolbar itself). Please help! I got it...... ns23-Jul-02 3:27 ns 23-Jul-02 3:27  I got it - paste was okay, you just have to go away from the toolbar item and come back and its inserted in the toolbar - something flaky but it works. Thanks anyways. ns NT4 project to Win2k project Claudius Müller23-Jul-02 2:57 Claudius Müller 23-Jul-02 2:57  Hallo ! I have any problems with an VC++ project, which I first build on a win NT 4 system. Now I have a system with win2k. I used the same VC++ compiler (version 6) on both systems. But I try to start the correctly compiled and linked project, startprocess of my application stops at the calling of the ProcessShellCommand function. I haven't any idea what the failure is. Can somebody help me ? Thanks a lot for all replies. Re: NT4 project to Win2k project Trollslayer (at work)23-Jul-02 6:21 Trollslayer (at work) 23-Jul-02 6:21  One suggestion which I find is needed when moving between Win98 and NT4 is to do rebuild all the files - go to the Build menu, then Rebuld all. This is because the precompiled headrs are differnt between Win98 and NT 4. Good luck Elaine Would you like to meet my teddybear ? Re: NT4 project to Win2k project ikarus24-Jul-02 0:01 ikarus 24-Jul-02 0:01  Hey ! Thanks for your answer, but I rebuild the source for more than one times on the new platform. And I didn't use precompiled headers, allways I compiled the complete project. Any other ideas ? CDC::GetTextExtent equivalent in GDI+ Williams23-Jul-02 2:48 Williams 23-Jul-02 2:48  Hi, Can someone tell me how can I get the width of a text to one determined font, cause I want to draw a rectangle that just fit around the text.

I have a problem with my SingleDocTemplate applicaation. When I quit, I have the following message in the debug window: Warning: destroying CSingleDocTemplate with live document. This causes a memory leak with my document. I tried to solve it for 3 days, but can't make it work. Please help me. Is this a genuine memory leak? Gavin Jerman23-Jul-02 2:44 Gavin Jerman 23-Jul-02 2:44  BoundsChecker is reporting the following code as a memory leak: void foo() { _bstr_t bstrA; _bstr_t bstrB; bstrA = "Fred"; bstrB = "Wilma"; bstrB = bstrA.copy(); // this causes the leak // this fixes the leak - bstrB = bstrA } At first I thought it was a leak, then I decided it wasn't, now I can't decide! Is it, or isn't it Gavin Re: Is this a genuine memory leak? Tim Smith23-Jul-02 2:58 Tim Smith 23-Jul-02 2:58  Yes, that will leak. "copy" will create a copy and then the assignment will create another copy since it can not assume that the original is free for ownership. bstrB = bstrA; bstrB .Attach (bstrA .copy ()); bstrB = bstrA .copy (false); These should all work just fine. But I don't do a lot of _bstr_t work. Tim Smith "Programmers are always surrounded by complexity; we can not avoid it...

Image size tracker problem chen23-Jul-02 2:02 chen 23-Jul-02 2:02  Hi, In a dialog based application, I have three resizable windows. The first one is used for a 2D curve and it can be resized in both of x-axis and y-axis directions. The second window (image container) only can be resized at x-axis and the third window only can be resized in y-axis direction. This looks like follows: ******************** * * * * curve (1) *(3) * * * * * * * ******************** * image (2) * * * ******************** Also I can change the size of the bmp image by using StretchBlt function. Now, I hope that the length of the image (not the length of the second window) should follows the length of the first window in the case of resizable of whole window. How should i do this? How can i get the length of the first window? Thanks in advance! chen Re: Image size tracker problem chen23-Jul-02 2:13 chen 23-Jul-02 2:13  sorry, the window changed when post above message. It looks like: 111111111111133333 111111111111133333 111111111111133333 111111111111133333 222222222222222222 222222222222222222 chen I'm a beginner,who can explain the VARIANT STRUCT to me?

Navin23-Jul-02 2:23 Navin 23-Jul-02 2:23  It has to do with COM and Automation. It is basically just a wrapper for any possible type of data you can transmit through Automation. I think it was designed like that to work with Visual Basic better... Even if you win the rat race, you're still a rat. Re: I'm a beginner,who can explain the VARIANT STRUCT to me?
