Code above doesn't look well . I paste it again .
IHTMLDocument2 * pDoc = NULL;
IHTMLWindow2 *pHTMLWnd = NULL;
IHTMLDocument2 * pFrameDoc=NULL;
IHTMLFramesCollection2 *pFramesCollection=NULL;
LPDISPATCH lpDispatch;
long p;
VARIANT varindex,varresult;
varresult.vt=VT_DISPATCH;
varindex.vt = VT_I4;
try
{
pDoc = (IHTMLDocument2*)(GetHtmlDocument());
if(pDoc!=NULL)
{
pDoc->get_frames(&pFramesCollection);
if(pFramesCollection!=NULL)
{
pFramesCollection->get_length(&p);
if(p>0)
{
for(int i=0; i<p; i++)
="" {
="" varindex.lval="i;"
="" if(pframescollection-="">item(&varindex, &varresult) ==S_OK)
{
lpDispatch=(LPDISPATCH)varresult.ppdispVal;
if (SUCCEEDED(lpDispatch->QueryInterface(IID_IHTMLWindow2, (LPVOID *)&pHTMLWnd)))
{
if(SUCCEEDED(pHTMLWnd->get_document( &pFrameDoc)))
{
BSTR bstr=NULL;
HRESULT hr=pFrameDoc->get_URL(&bstr);
ASSERT(SUCCEEDED(hr));
CString str= bstr;
SysFreeString(bstr);
pFrameDoc->Release();
pFrameDoc=NULL;
}
pHTMLWnd->Release();
pHTMLWnd=NULL;
}
}
}
}
}
}
}
catch(...)
{
};
try
{
if(pDoc != NULL)
pDoc->Release();
if(pFramesCollection != NULL)
pFramesCollection->Release();
}
catch(...)
{
};

It works perfect for me.

which site did you use for a test?
I would like to have a try.
Thank u.

I am still using this 2024. Your example is useful and helped me through the jungle. i is an integer not a string. varindex.lval = i;
Than things are working, already. Maybe someone else can use.

could you please prewrite this and post the complete .ccp and .h (containg the class)

Hi, I'm looking for a little help with some code I'm working with.
I'm still learning C++ and would like to use the PlaySound function to play a short (1sec) .wav file when iValue (detailed below) is an integer value of 15, and a different short .wav file if iValue = 14.
This is the code segment I'm currently working with:
if (iValue != -1) {
sprintf(acString,"%d",iValue);
} else {
sprintf(acString,"%s","None");
}
SetDlgItemText(IDC_VALUE,acString);
iValue shows an integer between 0 and 15 depending on input (and shows blank if there is no input).
I've been trying to get it to work for a while, any help would be greatly appreciated.

use switch
switch(iValue)
{
case 14:
PLaySound....
break;
case 15:
PlaySound....
break;
}

Hello,
Is there a way to get a file icon for a given file extension? I'm displaying a list of files that may or may not exist on the computer and I want to display the correct icon for each file.
I'm currently using a method that uses SHGetFileInfo, but this only works if the file exists on the machine.
Any suggestions?
Thanks,
Ian

According to the MSDN reference for SHGetFileInfo[^], you can use it to get information on the properties of a file extension "if the uFlags parameter includes the SHGFI_USEFILEATTRIBUTES flag".
The remaining problem is to get a list of file extensions of interest. Since you have a list of candidate filenames, you can use those directly. If you need to enumerate the extensions on the machine, the quick-and-dirty method would be to enumerate the keys under HKEY_CLASSES_ROOT in the registry.
Software Zen: delete this;

Could you not create a temporary file (with the right extension), call SHGetFileInfo, and then delete the file?

 Clever solution... I'll keep it in the back of my mind as a last resort...
Thanks.

Try ExtractIcon().
Otherwise, you'll need to call AssocQueryString() to get the executable associated with the file extension, load that executable using LoadLibrary(), and then call LoadImage() or LoadIcon() to get the icon's handle.

good afternoon, all
I am trying to get rid of one of the old link library from my application
I removed it from preprocessor definition, took all the link library files from LINK, but the program will still step into the area says #ifndef __XYZ_APP__ when I am doing debugging.....It really shouldn't behave like this, I also checked if anything like #define __XYZ_APP in header ....still no luck
does any body know why is this happening? thank you for your time

#ifndef __XYZ_APP__
this means: if __XYZ_APP__ is not defined, compile the code inside of me.
Since you undefined it, that is what should happen
|
|
|
|
|
a lot of confusion to me 
ok. Preprocessor symbols can be defined in two ways. (As I know)
1. in the source or header files
2. In the project setting. Please check the project settings, preprossor options..
BAsically All debug relateted preprocessor are defined in project setting only..

Is MFC in your DLL, if NO, then you two option either enable MFC in your DLL or call Win32 version of AfxBeginThread in your DLL like.. CreateThread .

Haven't you also received this compiler message about AfxBeginThread()? If not, why are you trying to end a thread that has not been started?

hi, i have a question about interfaces and templates: is it possible to have a function template inside a interface? see code:
__interface ITest {<br />
template<class T> void TestFunc(T& data, int size);<br />
}
is there an alternate method? i get a compiler error on this code. i am just getting started with templates
|
|
|
|
|
oops, sorry the formatter messed up my template<> brakets.
anyway i think i figured it out -- abstract classes are basically the same as interfaces, so use it:
template<class T> class ITest {
void TestFunc(T& data, int size);
// ...
};

Working on an interesting server application. On a private LAN this serever will handle about 120 clients(socket server) and at the same time it will communicate via 160 serial COM ports(COM server). For that we use multiple "PortServer" boxes by Digi which connect to LAN on server side and provide serial ports on the other. Digi's driver makes COM port control absolutely transparent. The idea is that the apps written for "classical" COM ports should work using "PortSErver" via LAN without a single code change.
Both socket and serial communication are implemented using IOCP. While socket server works fine the COM server starts eating up memory after some time. The nature of serial communication is a constant polling(and remote responses) @9600Bd on all 160 ports. Messages are only 6bytes long and all 160 COM ports hang on a single IOCP. This type of operation puts more strain on IOCP queueing mechanism than a typical LAN data stream. We are quite confident that the memory leak is not some silly thing in our code and here comes the question. Does anybody have experience with this type of IOCP application? I would really appreciate your comments.
Thanks,
Tom
