Does anyone know how to make an outlook style treeview where part of the node's text is black and bold, and the other part is blue and non bold. When you look at the folders, if you have any new messages it will look like the following.

Inbox (1)

The "Inbox" is black and bold, and the "(1)" on the same line is blue and normal font.

Been looking all over for some code on how to do this, but i see the same questions and no answers.

Thanks a lot.

Hello,

is there anybody who knows the command for this? I want to check if a program was shut down by an accident and then start it again (by using CreateProcess).

Thanks for any help

What distinguishes a program shut down by accident versus one shut down on purpose? Either way, there's no way to detect that if you did not actually start the program. Even then, the shut-down method used is questionable.

Hi,

I have and good old MFC/ATL application, that uses the Soap Toolkit 2.0 to connect with a web service, All works fine in my machine, but now I need to add the soap toolkit stuff to my installation set...

mmm... which MSI/Exe should I install ? How can I check if it's already installed ? I have downloaded from MSDN "soapsdk.exe" as "redistributable" but "sdk" doesn't seem for non programmer... point of view...

Thanks in advance, greetings

Hi All,

I have an application to download three XML files. Each one of them can be 1 MB or more. that makes my all of the system resources to be taken by it to download the file. I am downloading them from my server. I want to do something like this that i can compare the files local and remote one and if there are any changes i can just copy the changes to the local file. That will save my downloading whole files again and again even if they are same. can i do that. Please help..Any help or pointers are thoroughly appreciated....Thanks a lot in advance..

Regards,

Himanshu

One solution is to design the internal applications that processes the XML file to update a CRC check output for all the XML files. The client applications could quickly download the CRC output and compare it with the most recent downloaded one.

use the "If-modified-since:" header in your request for that file and send the GMT time of the last update date for the file you are requesting. The HTTP server will compare the time that you send with the time of the file and only send back the file on the server if it is newer.

IF your file is newer on your machine, you will get a status code 304 indicating that your file is newer.

Printing is really too lengthy a subject to discuss here. Instead, I refer you to Charles Petzold's Programming Windows, Fifth Edition from Microsoft Press.

You can still use the MFC helper classes such as CPrintDialog and CDC.

Hey,

I'll answer you cause I had the same problem about a year ago. I don't really know much about printing though, just gonna tell you what I did.

First off, I'd suggest you go to the Printing section on this website, there are plenty of articles on it, might have just what you need.

Other than that it really depends on what you want to print that's in the dialog. For instance I wanted to be able to print out the contents of a list box, which I was able to find a suitable printing class on this site. I'll go ahead and say that printing from any type of control can be done using a class similar to the one I had. If you're trying to print from something other than a control, can't help you much there.

throw or throw new?;

What is the correct way?

//error happens.
throw new Exception( "Error Message." );

or

//error happens.
throw Exception( "Error Message." );

What is the difference?
How is the new Exception deleted?

Thank You
Bo Hunter

It isn't. Or rather, it must be deleted by the catch block.

The method I usually use is something along these lines:

try {<br />
  // ...<br />
  throw BuilderParseException("AIEEEEE!");<br />
  // ...<br />
} catch (const BuilderParseException &ex) {<br />
  // ...<br />
}

The BuilderParseException that's thrown will be cleaned up at the appropriate time, and the catch-by-reference avoids a copy.

Its best to throw by value and catch by const-reference:

throw Exception( "Error Message." );
[...].catch (const Exception& e)
{cout << e.what();
}

How to programmatically setting power button action?

6-Oct-03 19:30

Does anyone knows how to set power button action in Window2000 & WinXP? I found the API WriteGlobalPwrPolicy() to do that. But, it can't work properly. After I involved this API the return value is nonzero. This is means this API is success. Even so, the system's global power button action doesn't have been change. The following code is my testing code, please help me to check it if it has any wrong. Or, you can tell me any tip to do it.

Testing code:

GLOBAL_POWER_POLICY gpp;<br />
 ReadGlobalPwrPolicy(&gpp); // get current setting.<br />
 gpp.user.PowerButtonAc.Action = (POWER_ACTION)2; //2:Sleep<br />
   <br />
 if(WriteGlobalPwrPolicy(&gpp) == 0)<br />
    TRACE(_T("Failed!\n"));<br />
 else<br />
    TRACE(_T("Successful!\n"));<br />
 ReadGlobalPwrPolicy(&gpp);<br />
 TRACE(_T("PowerButtonAc.Action:%d\n"), gpp.user.PowerButtonAc.Action);

I'm afraid I think you've drifted into custom control territory. You'll need to implement this one yourself.

You'll need to be familiar with the Windows drawing model and how to manipulate text and images within that model.

Excel Locale Issue

Derek Waters6-Oct-03 17:39

Derek Waters

6-Oct-03 17:39

G'day folks,

I'm attempting to write out a CSV file (don't ask) in a format that can be read by Excel (also don't ask) across Locales. Now, this is fine, I can format the numeric values correctly and then separate them using the locale's list separator. However, it seems that Excel only ever uses the System Locale list separator. That is, if some user overrides their separator (again, don't ask) to ',', Excel doesn't use that, but the original default setting for the locale (in the Italian locale, ';').

Is this behaviour expected? Sensible? A pain in the #$%?

Thanks.

Are you sure that Excel is supposed to use the locale's list separator? Maybe what Excel is dealing with is not considered a list. Anyway, once you have the data in Excel, you can use the Text to Columns menu option to fix the problem.

hello,
I'm fresh to VC,
I need an example for loading picture to PictureBox(control).
e.g., if I enter the file path, like c:\abc.bmp, then the picture will be loaded into picture(control).
I don't know which is good, using Hbitmap or Cbitmap.

Could anyone give me some example code?
Thanks.
