This is my first thread! The thread is initialized during WM_CREATE.
However their are no errors during compilation, but when I run it the program breaks.

void Windows7ProgressThread(void *)
{
if (TotalBytesToDownload)
{
if (List.AnyFailed())
{
TaskbarProgress->SetProgressState(g_hWindow, TBPF_ERROR);
}
else
{
TaskbarProgress->SetProgressState(g_hWindow, TBPF_NORMAL);
}

TaskbarProgress->SetProgressValue(g_hWindow,50,100);
}
else
{
TaskbarProgress->SetProgressState(g_hWindow, TBPF_NOPROGRESS);
}
}

The problem their are no errors, it breaks with error Access violation. :S

Even after I commented out what threading code I had written and the process.h header.
I run it and the same error is occurring over and over.

So single-step through the code until you find the offending line. If you think there are too many lines to wade through, read this thread on how to quickly narrow down a problem by removing unnecessary code.

It was because I removed the SUCCEEDED micro, but I can't believe the errors it gave me.
Thread exceptions and Access Violations.

I thought something went wrong with the project settings, cause it mentioned Multi-Threading.
Got WinMerge and started going over each line and started thinking what should be undone.

can scanf retain leading whitespaces

The SUCCEEDED macro did not cause errors to your code. How could it:

#define SUCCEEDED(Status) ((HRESULT)(Status) >= 0)

Hello,

Can scanf be set to retain leading whitespaces in between words?

For example, if the string was " Hello everyone, how are you today? "

can scanf grab " Hello" " everyone," " how" " are" " you" " today?"

Thanks,

Only if you wrote your own parser. The other ideas that I mentioned to you would use the space as the delimiter.

You can do this to capture everything till the enter key is hit.

scanf("%[^\n]", sz);

«_Superman_»

using sscanf in a loop

Hi,

How can I advance the sscanf statement to read each word in the sentence? Right now my output is an endless loop of "This".

CString incoming_line="This is my example incoming line.";
CString string_out;
while (sscanf(incoming_line, "%s", string_out )==1)
{
    cout<<string_out<<endl;
}

Thanks!

you could do something like this:

int offset = 0;
while (sscanf(incoming_line + offset, "%s", string_out )==1)
{
    cout<<string_out<<endl;
    offset += strlen(string_out);
}

Chris,

Thanks for your help.

I'm getting the following error when I use your suggestion.

Error	2	error C2666: 'ATL::CStringT<BaseType,StringTraits>::operator +' : 3 overloads have similar conversions

Any ideas?

Thanks,

You cannot use a CString object in this capacity.

Hi David,

Should I use "const char*" instead?

static text color and backgroung color

13-Apr-10 5:58

If you did, then how would scanf() be able to change its contents?

Since you are using MFC, have a look at CStringT::Tokenize() or AfxExtractSubString().
