Re: Crystal reports Control Monty220-Mar-02 2:06 Monty2 20-Mar-02 2:06  i did and added all those files too but it still won't register what if these fiels are yet to be copied and the setup tries to register the control or the setup copies all the files and then tries to register ?? Re: Crystal reports Control Bill Wilson20-Mar-02 6:16 Bill Wilson 20-Mar-02 6:16  What is the error code returned by regsvr32? Isuppose its possible to get InstallShield to screw up the installation order, but its probably not easy. Are there any dlls that cannot be copied until the system reboots? Does InstallSheield automatically reboot your system? If not, does it need to? If you manually restart the system, can you register the control? DC Blues Monty219-Mar-02 4:08 Monty2 19-Mar-02 4:08  how do i copy contents of one DC to another i tried BitBLit but it does't work here is the sample code OnDraw(CDC *pDC) { CDC memDC; memDC.CreateCompatibleDC(pDC); DrawStuff(&memDC); //Draw in mem dc pDC->bitblit(0,0,width,height,&memDC,0,0,SRCCOPY); } but nothing happens if i don't use memDC then Drawing is done please help Re: DC Blues Tomasz Sowinski19-Mar-02 4:20 Tomasz Sowinski 19-Mar-02 4:20  You need a bitmap associated with memory DC. Search CodeProject for CMemDC class - it'll do the boring stuff for you. Tomasz Sowinski -- http://www.shooltz.com Window Repainting #realJSOP19-Mar-02 4:07 #realJSOP 19-Mar-02 4:07  I have a weird little problem, and I think it's associated with DirectShow. I have an app that creates a CView-based window, and passes the hwnd to a DLL. The hwnd allows me to "attach" (don't know a better word at the moment) a live video preview to the window that was created in the app. When I move the child window/view around in the app's window, everything is fine - the window always repaints itself. However, if I move the window so that a portion of the client rect is clipped by the app window, when I move the child completely back onto the app window, the portion that *was* clipped does not repaint itself. I tried various API calls (MoveWindow, SetWindowPos, UpdateWindow, InvalidateRect, and RedrawWindow), but to no avail. Thinking the problem might be one of timing (a message was getting lost/ignored somehow), I put Sleep(1000); in the code just before my rectangle update. This caused the window to repaint itself correctly at first, but then after the one-second delay, *my* repaint occurred, and the portion that was previously out of view repainted as black. As an afterthought, I decided to just comment out the contents of my dll window repainting function, and exactly the same thing happens, so I know it's not my code that's causing this. Does anyone have any words of wisdom? PS. Both the app and the DLL use MFC, and I cannot add additional parameters that can be passed to the DLL from the app (architectural restriction, not mine).

Tomasz Sowinski -- http://www.shooltz.com Re: Window Repainting #realJSOP19-Mar-02 5:11 #realJSOP 19-Mar-02 5:11  I found the problem. I had to add the style WS_CLIPCHILDREN to the view in OnPrecreateWindow().

This all works fine, except I don't see how to change the icon that shows up in the shell for the application. I can easily change the icon in the app's caption/title bar, but not the the icon for the app that would show up on the Windows Desktop or in Windows Explorer. Any ideas on how / if I can do this? Thanks! Re: changing an application's shell icon Tomasz Sowinski19-Mar-02 3:50 Tomasz Sowinski 19-Mar-02 3:50  AFAIR, the shell just grabs first icon it founds in resources embedded in .exe. Tomasz Sowinski -- http://www.shooltz.com Re: changing an application's shell icon Chris Hambleton19-Mar-02 4:12 Chris Hambleton 19-Mar-02 4:12  Thanks for your reply -- that makes sense about what icon the shell grabs. However, is there any way to change which icon is displayed through the shell (like after the first time the app is run)?

What do you mean by 'like after the first time the app is run'? App only registers its file types, not the .exe icon itself.

If it's not there, you'll need to download recent Platform SDK from msdn.microsoft.com. Tomasz Sowinski -- http://www.shooltz.com Re: Cannot use COMBOBOX INFO Tomasz Sowinski19-Mar-02 4:43 Tomasz Sowinski 19-Mar-02 4:43  Set the cursor at tagCOMBOBOXINFO, then press Ctrl+J. You'll probably see this line: #ifndef NOWINABLE Then press Ctrl+J again. On my workstation it goes to the following line: #if(WINVER >= 0x0500) What's displayed on your screen? Tomasz Sowinski -- http://www.shooltz.com Re: Cannot use COMBOBOX INFO Tomasz Sowinski19-Mar-02 4:48 Tomasz Sowinski 19-Mar-02 4:48  Post the #define WINVER and #includes. You've screwed something - maybe WINVER is #defined too late. Tomasz Sowinski -- http://www.shooltz.com Re: Cannot use COMBOBOX INFO Tomasz Sowinski19-Mar-02 4:53 Tomasz Sowinski 19-Mar-02 4:53  Move #define WINVER 0x0500 into stdafx.h. It must be placed before #includes.

Here's one way to store and print your array: void printArray(char *array); int main(void) { char array[] = {'-','-','A',...,'Z'};//enter all letters of the alphabet printArray(array); return 0; } void printArray(char *array){ //code to print it in whatever format you need } ralf.riedel@usm.edu
