Hello everybody,
Does anyone know easy way to get any urls sourse code?
For example:
It means, it should get sourse code of www.codeproject.com (html code) without open it on
any browser.

i found out this is the easy way to get sourse code of any url:

void CFreeSMSDlg::OpenURL(void* param)<br />
{<br />
	CInternetSession mySession;<br />
	CHttpFile *pHttpFile;<br />
	CString url,tmpStr;<br />
	char inBuf[500];<br />
	memset(inBuf,NULL,sizeof(inBuf));<br />
	UINT nBytesRead;<br />
<br />
	CFreeSMSDlg* pThis;<br />
	pThis = (CFreeSMSDlg*)param;<br />
	bool bNotFinished = true;<br />
	<br />
	do<br />
	{<br />
		try<br />
		{<br />
			// Open HTTP file<br />
			pHttpFile =(CHttpFile *) mySession.OpenURL(pThis->pUrl);<br />
		}<br />
		catch (CInternetException)<br />
		{<br />
			::MessageBox(NULL,_T("Received Exception from OpenURL()"),_T("Error!"),NULL);<br />
			bNotFinished = false;<br />
		}<br />
		if(pHttpFile == NULL)<br />
		{<br />
			::MessageBox(NULL,_T("Error in OpenURL"),_T("Error!"),NULL);<br />
  		    bNotFinished = false;<br />
		}<br />
		else<br />
		{<br />
			nBytesRead = pHttpFile->Read(inBuf, sizeof(inBuf));<br />
<br />
		}<br />
<br />
	} <br />
	while (bNotFinished);<br />
		<br />
	pThis->bIsSent = true;<br />
	_endthread();<br />
<br />

Hi all,

Can anybody tell me is there any other api for finding resource handle except AfxGetResourceHandle() in vc2005

thanks in advance...

Hello there,

I believe that AfxGetResourceHandle() is simply returning the allocation base of the module which contains the resource your attempting to access. This is so it can correctly calculate PE image offsets. Therefore you should be able to simply do the following:

If the resource is located inside the module your executing code from you can do this:

#define MyGetResourceHandle ((HINSTANCE)&__ImageBase)
HICON hIco1 = (HICON) LoadImage(MyGetResourceHandle,MAKEINTRESOURCE(IDI_ICON1),IMAGE_ICON,16,16,0);

What about save the Bitmap to stream (Image::Save)[^], where the stream resides in memory (CreateStreamOnHGlobal)[^] and then writting the stream to file CArchive::Write. Reverse the process for loading object CArchive::Read, CreateStreamOnHGlobal, Bitmap::FromStream. overload << >> on CArchive for insertion and extraction.

ABOUT CONCATINATION

Hi everyone,
i am doing concatination in my activeX control project.means i am having two varibles one is MemId is of type LPCTSTR and another one is strmsg is of type char *strmsg.this is in read block function.
i am doing like this:
MemId=dStr;
strmsg=strcat(strmsg,MemId);
MessageBox(strmsg);
it is not giving error but when i execute my actual program in that i used this activeX control. that time is giving send error or dont send error message box.
afterwords i changed this to for first time i used string copy function but it is also giving same error.
Please Help Me what's wrong with my code.

Have you allocated strmsg?
possibly you are not allocating char *strmsg; you need to allocate memory for the string. something like char strmsg[YOUR_STRING_SIZE]; char *strmsg = new char[YOUR_STRING_SIZE];

savitri wrote:
strmsg=strcat(strmsg,MemId);

It seems your module is not unicode as strcat doesnot give error at compilation taking (char *, LPCTSTR).

And as a side note, IMHO, when you are using generic string data type LPCTSTR always use generic text manipulation API's and data structure, use _tcscat inplace of strcat.
Unicode, MBCS and Generic text mappings[^]

generic text apis start with _tcsxxx search in msdn index when you want a mapping to string functions with strxxx

if you specified parameters for scanf correctly, the above, then the stack overflow is due to the stack allocation int count[10001][10001]; which is "10001 * 10001 * sizeof (int)" which is very large than the default stack size which is 1MB. To increase the stack size /STACK (Stack Allocations)[^].

It is better to allocate in heap.

And also array size in main 1001 and size in MinOperation 10001 check it for logic of your program (Any way int count[1001][1001] is also going to issue stack overflow).
