Go to sourceforge.net and search for "HTTP proxy". There are several projects under work that may suit your needs.

Hi,

I am trying to thorughly test out some image processing code I have developed using GDI+.

I am wanting to test it with bottom-up scanline images, btw. the stride member of the bitmapdata class indicates this.

My problem is where can I get a bottom-up scanline image from!

Cheers
Richard

all bitmap files are bottom-up scanline. so a LoadBitmap might be what you need.

Out of Memory error

All of a sudden I'm having trouble opening my workspace in Visual C++ 6.0. When I try to open the workspace, it acts as if it's opening and has the status bar at the bottom to make it look like everything is fine, but then nothing comes up. No files open and the classview information doesn't show up. If I open up another workspace and then try to insert the project into that other workspace, I get an error message that just says "Out of Memory". Any ideas on what might be happening?

It started after I tried to run my program in Debug mode and my system blue-screened on me. I had to turn off my computer and then turn it back on and ever since then, it's been giving me this error.

No good answer, but the first thing i would do is delete all the .opt, .ncb, .aps, .clw, .plg and *.pch files in that project's folder(s) (these are all created as part of the build process).

Only one thread accessing the CList object

10-Jun-02 2:56

I want a sample program to create two threads & only one thread access the CList object at a time. that is, one thread uses some(i don't know which) synchronization object to lock the CList object & writes to it and then releases the CList object. Next another thread does the same process, but instead of writing, it reads from the CList.
can anybody help?

I'm sorry but time is not my friend right now to make an example, but you can start searching for this on MSDN: CMutex or CCriticalSection.

Hope this helps.

PS: if you have installed the MSDN Help from Visual Studio.NET then use this address:

You should use something like this:

CCriticalSection cs; // this object must be global of static in your class

// then in the function that access the CList
void CMyClass::FunctionThatAccessTheCList ()
{
  // lock this section, begins the synchronized section
  cs.Lock ();
  //.... modify the list here

  cs.Unlock ();
  // end synchronized section
}

Is there any limits to how long a PATH+FILENAME can be?

redeemer10-Jun-02 2:46

Is that MAX_PATH*2+1 ?

I always thought the whole thing's max length would be MAX_PATH (plus 1 for the terminating NULL)? But this is only true on 9X systems - I think there are ways of getting Windows NT-based systems to have UNICODE paths much longer than MAX_PATH.

But since I never compile in Unicode, I always just use MAX_PATH + 1 and hope for the best. Smile | :)

No generalization is 100% true.
Not even this one.

Moving the Cursor in ComboBox

10-Jun-02 2:29

I am trying to reposition the Cursor inside of the Edit Box in a ComboBox in my Application. I've tried SetCaretPos, but it doesn't seem to affect the ComboBox Control.

What I'm doing is trying to get an autocompleting ComboBo that Set the Cursor to the Beginning of the Selected string that holds the completed text instead of the end. Right now when I auto complete the text the control scrolls to the end of the text and so you can no longer see what you are typing.

CEdit * pMyEdit = (CEdit *)m_myCombo.GetDlgItem(1001);

this will get the CEdit part of the combo box. you can do the SetCaretPos on that.

Re: Moving the Cursor in ComboBox

I've tried that or at least something simillar. I have the Edit Box subclassed. I put this code inside of the OnEditChange of my ComboBox
class and the Cursor never Budges from the end of the string.

CEdit* lpEdit = static_cast<cedit*>(GetDlgItem(1001));

lpEdit->SetCaretPos(CPoint(0,0));
