Re: Question on prefix and post fix Vadim Tabakman28-Jun-04 19:58 Vadim Tabakman 28-Jun-04 19:58  I tried to compile that in some code, and didn't succeed at all. it didn't like the ++ after the 5. I believe it expects a variable. so i'm not sure how you got that to compile why are you doing ++++ anyway?

I require it to be multipart/form-data. No big complaint I thought so added this line: Connector->Property["RequestHTTPHeader"] = "Content-Type: multipart/form-data"; But instead of changing the current Content-Type it added a new line. ie: Content-Type: application/dime Content-Type: multipart/form-data What I need to know, is how to change the Content-Type in the HTTP Header.

A question to COM gurus Anonymous28-Jun-04 19:28 Anonymous 28-Jun-04 19:28  I don't seem to have a whole lot of success getting any feedback on the COM forum, so I thought I'd try it here instead. Here's the question: how do I find out which CLSID was used to create a COM object (as an argument to CoCreateInstance), assuming I only have a pointer to that object and the object doesn't support IProvideClassInfo? Here's a bit of background: I am trying to add filters to a DirectShow filter graph, and the graph itself is quite capable of creating additional filters under the covers. Once created, these filter objects can be enumerated, which gives me pointers to them. What I need to know, though, is what kind of filters were created. BTW you don't really need to understand this part, the point is that I know nothing about the object except for the pointer itself. Thanks, M.C.

Get Window HANDLEs of a Process Abin28-Jun-04 18:08 Abin 28-Jun-04 18:08  Having the process ID or HANDLE of a particular process, is there a way to find out its main window(or enum through all windows those were created by that process)? Thank you. Re: Get Window HANDLEs of a Process JimRivera28-Jun-04 18:32 JimRivera 28-Jun-04 18:32  Ok i am new to answering question but i think your asking if you have a handle can you find out whether it is a child and then get the main window. If I am right then use: BOOL IsChild(HWND hwndParent, HWND hWnd); MSDN Library Lookup for IsChild Ok so now you have checked your handle and its a child. Now you use: HWND GetParent( HWND hWnd ); MSDN Lib: GetParent I hope this helps Discovery consist of seeing what everybody has seen and thinking what nobody has thought -- Albert Szent-Györgyi Name the greatest of all the inventors: accident --Mark Twain CScrollview printing?? xxhimanshu28-Jun-04 18:00 xxhimanshu 28-Jun-04 18:00  Hi, I am having a csrollview where some data is being rendered. I want this data to be printed..I am unable to find anything on it.. can anyone help me out.. there is also a small problem.. like I have the vertical and horizontal scrollbars attched to the same.. but the vertical scrollbar is not working the way it should.. I mean if i drag the bar by mouse it either goes up (max) or below (min). I want to drag it by mouse and remain there where i leave.. Hope that both can be solved.. Looking forward to a solution from you people. Thanks a lot in advance..

Leo Avoiding a memory leak georgiek5028-Jun-04 16:21 georgiek50 28-Jun-04 16:21  I have a function that returns a char* and would like to know which way to handle this as to avoid a leak. If the function were in this format char* Function(void) { char *szString = new char[50]; return szString; } And was called like so: char *szBuffer = Function(); would deleting szBuffer like so: delete szBuffer effectively erase the allocated memory?
