Hi,
I have a progress bar and I set the range using
m_datprog.SetRange(0,Prog)
The problem I have is that the progress bar is full before it reaches the maximum limit (prog). Any help would be appreciated.
Thanks,
DS

Hi,
Are you using a timer with the progress bar?
Cause it sounds like you just set the progressbar, but never increment it?!

See CProgressCtrl::SetPos(...)

If you set the control's range with SetRange(0, 100), and then call SetPos(125) part-way through some process, the control will indeed show 100% even though the process is not done. Does that sound like what you might have?

Does any one has the idea of the exact calculation for superscript and subscript style of font. I mean the font is shrinked in MSWord. What calculation is used ? and also the baseline are moved as well. What are the standard calculations behind it ?

Hi, all
I encountered a problem about refreshing the system drivers in Device Manager. When installing a software, I registered 2 system virtual device into system. After the box restart again, those 2 drivers do not display in the "No Plug and Play Device" device node in the System Device manager(via "View" menu and "Show hidden devices"). It will always appear after running "Scan for Hardware Change" menu or the seconde time reboot.
I want to ask is there any Windows API or MSDN function can play the same role as "Scan for Hardware Change". I want to let Windows do the same job.
I tried the sending message way and it was failed. The following are my codes.
SendMessageTimeout(HWND_BROADCAST, WM_DEVICECHANGE, DBT_DEVNODES_CHANGED,0, SMTO_ABORTIFHUNG, 3000, &dwMsgResult);
Thanks for give me some suggestions.

I want to write a program in Visual C++ to transfer data between a computers and microcontroller.
I have to use the wireless communication between PC and Microcontroller.
What i need (libraries, or is there any help in MSDN.)
What i figured out is that i need "winsock" for programming.
Where should I start.
thanks

Hallo,
In my program, I execute some SQL-querys stored in a CString-variable. My question is: how long can this query be? Does this depend on the CString or on SQL?
Thaks, Gerhard

of course limitted by the SQL engine... by i never heard of a query maximum length size...

Hi All,
I have been trying to build on an application that allows you to write to blogs. After googling and gathering information I have not been able to find a good resource that provides some articles on writing to blogs. I am using VC++ .NET
Can some body provide a URL where I can get some examples regarding publishing to blogs?
Any help is highly appreciated.
Thanks

Thanks for your suggestion.
Can you tell me how can I use this API to write/publish the comments to blogger.com

Each blog uses a different API to do this. Almost all of them use an HTTP-XMLRPC type setup, but you will have to look at the documentation for each blog you want to write a client for to find out what they want/expect to be in the message. I would start with the open source blogs first (LiveJournal use to have a fairly extensive document that described their API in great detail ... I'm not sure if it is still there or if it is up to date, but it would be a good starting point).
If you decide to become a software engineer, you are signing up to have a 1/2" piece of silicon tell you exactly how stupid you really are for 8 hours a day, 5 days a week

Thanks for your comment. I already know that it would require an API for specific blog.I want to write to blogger.com

I hava writen a DLL,and injected DLL into a process.But when I inject DLL into target process every time,it will terminate the target process.If I don't create a new thread in DLL,it work well.How can I write correct code to implement?
ps: testdll.cpp
#include "stdafx.h"
#include <afxdllx.h>
#include "process.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#endif
static AFX_EXTENSION_MODULE TestDLL = { NULL, NULL };
unsigned __stdcall ThreadFunc(LPVOID pParam){
CSocket sockListen,m_sockSend;
sockListen.Create(6802,SOCK_STREAM,"127.0.0.1");
sockListen.Bind(6802,"127.0.0.1");
sockListen.Listen(5);
sockListen.Accept(m_sockSend);
Sleep(50000);
sockListen.Close();
MessageBox(NULL,"ThreadFunc","Oops!!",MB_OK);
return 0;
}
extern "C" int APIENTRY
DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID lpReserved)
{
UNREFERENCED_PARAMETER(lpReserved);
if (dwReason == DLL_PROCESS_ATTACH)
{
TRACE0("Test.DLL ！\n");
if (!AfxInitExtensionModule(TestDLL, hInstance))
return 0;
new CDynLinkLibrary(TestDLL);
_beginthreadex(NULL,0,ThreadFunc,NULL,0,NULL);
}
else if (dwReason == DLL_PROCESS_DETACH)
{
TRACE0("Test.DLL ！\n");
AfxTermExtensionModule(TestDLL);
}
return 1;
}

perhaps I should write dll without MFC

plz give me sample code useing this method.
