Normally you can't create a progress bar for that because the msinfo32.exe does all the work for you and does not provide a callback or notify system.

Don't try it, just do it! Wink | ;-)

Instead of

WaitForSingleObject(ShExecInfo.hProcess,INFINITE);

you can wait for a specific amount of time:

do{ <br />
  dwWaitResult = WaitForSingleObject(ShExecInfo.hProcess,INFINITE);<br />
  switch( dwWaitResult ){<br />
  case WAIT_TIMEOUT:<br />
    // still processing, update progress<br />
    break;<br />
  case WAIT_OBJECT_0:<br />
    // applicaiton is done<br />
    break;<br />
  case WAIT_FAILED:<br />
    // something else is wrong<br />
    break;<br />
  }<br />
}while( WAIT_TIMEOUT == dwWaitResult );

I truly CRINGE every time I see an INFINITE wait, anyhow.

system font size

hi,guy

Sometimes the big font(120 DPI) will cause the interface to look so bad when we expect software to be run under small font(96DPI) conditions.
This problem has troubled me for a long time.
Do you have any solution or advice to me.
Thank you for help me!

Best Regards,
KHLin Smile | :)

You will need to layout your application so that it looks acceptable at either desktop font size. If the current layout is too crowded, you should rethink how you are doing things.

Another option is to dynamically resize the controls in your application. Take a look at the articles in the 'dialog' section here on Code Project for some ideas.

No Unicode in Status Bars?

Can you not use Unicode strings in status bars?? The lParam of the SB_SETTEXT message is a LPSTR (not LPTSTR)...

Thanks for the reply. I have another question - the SB_SETUNICODEFORMAT message says it needs comctl32.dll version 4.00 or later but the Remarks section says to see the remarks for CCM_GETUNICODEFORMAT which says it needs version 4.71 for WinNT or version 5.80 for Win95/98. Do you know which version it needs?
- thanks

I installed VS 2005.NET Beta 2 (the VS not an express edition) and I realised when making an MFC Application it has the same menus and buttons strips are equal to the 2003 version... I was expecting the same design of the Office 2003, since that happens when working without MFC...

Is this just my ignorance on MFC, or MS will change that soon?

Function call overhead

When I generated the assembly code for both inline and non-inline function calls, I see no difference in code, they're exactly the same.
But it said to be inline version does not have the function call overhead? D'Oh! | :doh:

inline is a suggestion to your compiler, it's not obliged to take your advice. I'm not sure if the compiler is allowed to inline without the keyword, though.

It is, if you specify /Ob2.

Quoting from MSDN:

/Ob2 Expands functions marked as inline or __inline and any other function that the compiler chooses (expansion occurs at the compiler's discretion, often referred to as auto-inlining).

/Ob2 is in effect when /O1, /O2 or /Ox is used.

This option requires that you enable optimizations using /O1, /O2, /Ox, or /Og.

I believe that the inline keyword has no effect when you are compiling for debug.

Also, the compiler treats inline only as a suggestion, not as a requirement. This means that if the function is large enough, is called in a lot of places, or some combination of the two, it may decide to not generate code for it inline.

Hi,

I'm tring to control ICQ from a small external MFC app.
I'm doing it with Spy++ to identify the massages related to the action I want to simulate, and then sending those massages to the ICQ contorls with PostMassage function.

Now, my problem is - how to control the TreeList control (with the pepole names) within ICQ ?
What I want to do, is to open a chat window for each of the members in the list control... In the ICQ it's done by double-clicking on the user-name in the list control. but I didn't succses to understand how to do it manually with Windows-massages....

Actually, that question is related not specifically to controlling ICQ, but in general to remote control a treelist control in WINDOWS.

10X !

I'm not even sure if the user list control is a tree view. The only way to find out how to remote control it is Spy++ or other monitoring software.
You have to monitor all the messages that are sent to the control, find out what parameters they have, how they work, ..., and so you will be able to get a handle to the list control from your application and send messages yourself.
It could take some time, but that is the way I'd prefer.

Hello,

I try to use the following code in the MS-Sample: "Browse".

SendMessage(hwndHTML, DTM_DOCUMENTDISPATCH, 0, (LPARAM) &pDisp);

pDisp->QueryInterface(IID_IPIEHTMLDocument, (void**)&pHTMLDocument);

but I get the Link error:

LNK2001: unresolved external symbol IID_IPIEHTMLDocument

Requirements
Pocket PC: Windows Mobile 2003 and later
Smartphone: Windows Mobile 2003 and later
OS Versions: Windows CE .NET 4.2 and later
Header: htmlctrl.h
Library: htmlctrl.lib <- This wrong - this file doesn't exist. I think it must be htmlview.lib.

I use the following lib files

aygshell.lib
htmlview.lib
gx.lib
webview.lib

I get the Link-Error with C++ 4.0 and with Visual Studio 2005.

What is wrong ?

Thank you for your help.

I (and a couple of other people I have found out) have asked how to draw lines in RichEditView/RichEditCtrl. So far, no one has been able to answer the question. Anybody got an idea of how to do it?

Re: Drawing Lines

Subclass the control using SubclassWindow, then handle the WM_PAINT message and draw your lines there.However you might need to handle some additional messages as well as scrolling, resizing, etc. could be involved.
Hope this helps.

I am using the RichEditView/Doc architure. I am using it so I can use formating as well as use the EN_LINK messaging. Will this interfer with the message handling in the RichEditCtrl?

Re: Drawing Lines

Not if you are going to call DefWindowProc. Actually you will need to call this function because you will want first the RichEdit to display normally and after that make your changes.

You will most likely need to write a simple parser that can identify the location of the function in the cpp file. You can use tools like yacc, bison. Or, if you know the signature of the function (return type, type and no. of params) just search for a regular expression that will match.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
