I had problem in migrating from VC6 to VC2005
typedef _A::size_type size_type; works fine in the vc 6 and flashes the below error after migrating to VC 2005
"thirdparty\dinkumpatches\xstring(39) : error C2146: syntax error : missing ';' before identifier 'size_type'"
pls advice

it looks like the "_A" isnt defined. Look where it was defined in the VC6 and than you why it isnt defined in VS2005. I guess it is a define which surrounds the "_A".  Bad code

Hi all,
In mfc I use CInternetSession to download files from an http server. What can I use via WTL?
Thanks,
Jayjay

Thanks,
Sorry what i meant was what can i use for ATL not WTL an ATL version of CInternet session.

You should be able to use this with ATL, it just wraps the WinInet API.

Hi,
Will the distribute mfc libraries? Or even static link?
Because I think this still will.
Thanks,
Jayjay

Look at the code he pointed at - the only thing it references is WinInet - which is distributed as part of Windows, NOT MFC.
If you're conversant with the MFC classes, as you are, you're not going to find anything much easier or better than that wrapper - the only change I'd make would be to wrap the classes in a namespace so the names don't collide with MFC.

Thanks I am now using it, now I can't understand how I can write a file that i have downloaded.
Here is my code:
<br />
CString strStaus;<br />
CInternetSession Session(_T("Test Application"));<br />
CHttpConnection Connection1(Session,_T("http://10.5.1.4/downloads/Managepoint/ManagePoint431InstallerBuild_55.zip") ) ;<br />
BYTE Buffer[4096];<br />
<br />
<br />
CHttpFile File2(Session,_T("http://10.5.1.4/downloads/Managepoint/ManagePoint431InstallerBuild_55.zip") ) ;<br />
for (DWORD dwRead2;dwRead2=File2.Read(Buffer,sizeof(Buffer)) ; ) <br />
{<br />
}<br />
Thanks,
Jj

CHttpFile File1(Connection1,_T("GET"),_T("/"));
File1.SendRequest();
ULONGLONG const nBytes = </code><code>File1.GetLength();</code>
<code>BYTE* bytes = new BYTE[</code><code>nBytes</code><code>];
File1.Read(bytes ,</code><code>nBytes</code><code>) ;
HANDLE hFile = CreateFile(some-file-name, GENERIC_WRITE, 0, 0, CREATE_ALWAYS, 0, 0);
DWORD bytesWritten;
WriteFile(hFile, bytes, (DWORD)nBytes, &bytesWritten, 0);
CloseHandle(hFile);
I've assumed the file you're downloading is < 2GB (should be a safe assumption) and haven't put in any error handling. But that should work.

Thanks what i did to write was
<br />
for (DWORD dwRead2;dwRead2=File2.Read(Buffer,sizeof(Buffer));)
{<br />
fwrite(Buffer, sizeof (char), dwRead2 , pFile); <br />
}<br />

monsieur_jj wrote: How can I prevent the re-download of the file if it is already successfilly downloaded because the problem is that after i successfully downloaded the file and restarted my program it downloads again and adds the files to the complete files thus doubling the size of the file and making the file useless.
Check for file existence when starting the download process - if the file you want to write is already present, you need to take some action, whether it's overwriting the file or writing to a differently named file.

I got the writing sorted out however im still looking for ways to have a pause resume capability,
<br />
BYTE Buffer[4096];<br />
<br />
CHttpFile File1(Connection1,_T("GET"),_T("/"));<br />
File1.SendRequest();<br />
for (DWORD dwRead1;dwRead1=File1.Read(Buffer,sizeof(Buffer)););<br />
<br />
CHttpFile File2(Session,_T("http://www.codeproject.com/"));<br />
for (DWORD dwRead2;dwRead2=File2.Read(Buffer,sizeof(Buffer)););<br />
I am getting an error C2668 'function' : ambiguous call to overloaded function at File1.
what can i do to resolve this?

hey every one...i have a prob.....i am making a program which will generate an exe...i want when i run my program....it should make a text file which is not a problem and one exe file...which is some other program that i built......not the same as the program from which im making this exe....what should i do for that??? i just had a random idea in my mind...i though every file is a file...why not try like text file..so i changed the extension of the exe(that i want to generate by running other one i.e. exe that i want to produce) in txt...then copied that into fputs("all the converted file contents here", outfile)....then tried to run...changed all escape seqence and all( like " changed to \" )...but didn't work as i expected....i knw its a very lame idea.... ...can someone tell me how to do this....any idea guys??/

This is not really an ATL, WTL or STL question. But, as I'm a nice guy, I'll suggest you open your files in binary mode (fopen(filename, "rb") or fopen(filename, "wb"), so that the C run-time doesn't do any translation of line-ending characters.
Alternatively (and this is better), you can embed the executable file you want to write as a resource in the program that is generating it. Here's a function that should load and write a named resource:
#include <Windows.h>
#include <ShlWApi.h>
bool WriteFileFromResource(HINSTANCE hmodResource, LPCTSTR name, LPCTSTR type, LPCTSTR destination)
{
if (!type)
type = ::PathFindExtension(name) + 1;
HRSRC rsrcFile = ::FindResource(hmodResource, name, type);
if (!rsrcFile) false;
HGLOBAL gblFile = ::LoadResource(hmodResource, rsrcFile);
if (!gblFile) false;
DWORD sizeFile = ::SizeofResource(hmodResource, rsrcFile);
if (!sizeFile) return false;
LPVOID filePointer = ::LockResource(gblFile);
if (filePointer)
{
bool ret = false;
HANDLE hFile = ::CreateFile(destination, GENERIC_WRITE, 0, 0, CREATE_ALWAYS, 0, 0);
if (hFile)
{
DWORD nBytesWritten;
ret = (::WriteFile(hFile, filePointer, (DWORD)sizeFile, &nBytesWritten, 0) && sizeFile == nBytesWritten);
::CloseHandle(hFile);
}
::FreeResource(gblFile);
return ret;
}
return false;
}

I need to develop a COM dll which will read data from a serial port.
I am very new to COM programming.
Please help me regarding this. 
|
|
|
|
|
What is the problem ? Where are you stuck ? What did you try so far ?
|
|
|
|

I just learnt to create a simple object in ATL.
Now my requirement is to write an object which will open a serial port and read data from it.
I got some code which will make use of CreateFile and read data from it.
But i dont know exactl where can use the code what will be the function return type because i am developing a ATL dll.
So i am unable to procede further.

Hence you need to go deeper inside documentation.

Hi,
We have this piece of code in OnSheetInitialized():
// Add minimize button to the standard property sheet.
this->ModifyStyle(0, WS_MINIMIZEBOX);
This seems to work on XP, but not on Vista (with Aero turned on).
The minimize button shows up correctly, but on clicking it nothing happens on Vista(with Aero).
I set a breakpoint in CPropertySheetImpl::OnSysCommand, and on Vista with Aero turned off, it breaks into this handler on clicking minimize, but doesn’t do so when Aero is enabled.

i created a dll....that uses the function..

//some code here.....
}
BOOL APIENTRY DllMain (HINSTANCE hInst /* Library instance handle. */ ,
DWORD reason /* Reason this function is being called. */ ,

break;
}
/* Returns TRUE on success, FALSE on failure */

}
when im compiling this dll with Dev-C++ compiler..im getting error....
my compiler log is:

can someone please help me what im doing wrong...what im able to understand is that it is not able to get the declaration for LRESULT......
how to correc that.....
thanx in advance...dudes

Two remarks first: this is not the correct forum, it is more related to the C++ forum. Also, please format your code properly using the PRE or CODE tags, it will be much easier to read.
Now to your problem, did you include windows.h at the top of your file ?

Dear friends,
I want to make a Internet Explorer plugin which works like mcafee siteadvisor browser plugin. When user does a google search, it should be able to show the rank as per my specifications on the result list of google search. The ranks are in scale of 0-10 and will be shown as and where mcafee siteadvisor shows the green red coloured buttons.
To me the key challenge area is to grab the google search result list, and then show the scores on the google search result page. Do I need to use dhtml/javascript?
Thanks in advance
Bikram...

Hi all,
I'm writing a toolbar for IE. I want to open a menu (or a simple window - not a dialog) that will open outside of the toolbar space (but inside IE).
I want to catch the mousemove, and to draw my own graphics which change depending on the mouse location.
I tried using TrackPopupMenu, however I didn't find any way to catch the mouse-move, or to draw the menu on my own.
I'm using WTL.
Thanks a lot,
Amos
