Hi Friends,
I developed a desktop applcation in .NET 1.1 frameework using C#.
The application works perfect in Windows XP or Windows 2000 Server environment, but in Windows 2003 server the application is really slow. The performance is degraded upto 200%. i.e. it takes 4 times more time in Windows 2003 server than under Windows XP or Windows 2000 server.
Can anyone tell me what is the problem and can it be rectified.
Thanks,
Sushant Duggal.

Nope. We don't know anything about your code or what your app is doing. If you give us some details, we might be able to suggest something.

Hi Dave,
My application is a mail sending application using cdosys.dll. i have used threading concepts to enhance the performance of the application.
but the performance is so bad in win2003 server

This doesn't help much. You'll have to profile your code on the Server to see where the problem is.

Hi,
Can you tell me what do you mean by profiling the code???
Thanks,

It means that you use a code profiling package to log the time it takes to execute sections of your code. This will tell you where the bottleneck is so you can troublehsoot your problem.
Here[^] is a trial version of a profiler.

Hi,
check if the server is ok. I once had a similar situations and begun profiling my application. After several days a figured out that the hard disk was slow because of a badly configured raid system. It could have saved me several days if I just had called our admin to tell him to fix the raid.

Thanks Robert,
But I tried it on two systems, ans I faced the same problem.
Can you tell me about profiling.

Hi,
in short:
1. Compile your app in Debug mode and put it onto the server.
2. Download and install a profiler on the server (NProf[^] is a free one).
3. Start NProf, select your application and make a test run.
4. In case of NProf the application must shut down before it shows any results.
5. Analyse the results to find which part of your app is slow.

Hi,
Does anyone know if there's functionality available in .NET (using C#?) to
export data from a Windows Application into a PowerPoint file format? For
instance, if I'd a form containing a bitmap image in my Windows App, I need
to save that to a slide in the PowerPoint file.
Any ideas/info is appreciated.
Thanks

I'm writing an FTP utility and had wanted to dispay/allow user to update the ip address, user id and password in toolstrip text boxes. My issue - for which I have a work around is that the .net toolstrip textbox control does not allow for masking characters.
I'm interested to hear some options that others may have used to solve this deficiency in the control.

The controls that come with the .NET Framework are a basic set of controls. They're not meant to be the "Be All, End All" of the Utimate ToolBox. If you need specific functionality, there are two methods of getting it. Either find and buy a commerical control library that offers the functionality you need, or (my personal favorite!) write it yourself!! That's what inheritance is for and why you have the Control Library projects in Visual Studio. You can make your own version of the control with the added functionality tacked on.

Hi guys -
When using the 'System.Configuration.ConfigurationManager.AppSettings("key")', it seems like it can only access the config settings defined for the primary assembly running in the app domain.
i.e. i have a program
MasterApp.exe
SOAPProxyLib.dll
Now, if i declare the following AppSetting value in the SOAPProxyLib.config:
<br />
<add key="key" value="value"/><br />
And then invoke it
<br />
Dim lstr As String = System.Configuration.ConfigurationManager.AppSettings("key")<br />
It returns nothing, but if i declare it in the MasterApp.config, this works fine, called from the SOAPProxyLib.
Is there any way i can put the settings i want for the library in the libraries config settings, and manage them independently to the rest of the app?
Cheers
Tris

That's right! Only application get to use config files. DLL libraries do not get their own config files. This is because a DLL becomes a part of the process (or application) that's calling it. Anyone using your library has to be aware of the fact that they must put any configuration information your library needs into the applications config file.

No there isn't. You'll have to write one if you want it.

Not quite sure what you want, but you should look into the Calendar Class

Hi,
I would like to implement a textbox into my application that allows the user to enter hex, decimal or binary values (based on the selection of a radiobutton group.
For hex values, for example, I would like the entered data to be byte seperated by spaces like this: "0E 3C 32...". I was thinking that a masked textbox was the way to go, but a masked textbox only allows for a fixed length mask, it seems.
AFAIK it is not possible to specify a mask that is repeated for the length of the entered data.
Do I have to parse the content of the textbox and reset the contents whenever the user enters a single character, or is there a much simpler solution?

For a masked textbox you don't have to fill all of the mask spaces, so a mask: ###, can have a legal input of "1".
You can also set the mask to lengthen itself when the user wants to enter a number longer than the set mask.

I am trying to get the user and domain of a running process. I can do it using the WMI, but this has various problems (it's slow, it needs to run wmiprvse.exe). There must be a way of getting this information without using the WMI - does anyone know it? (I'm using C# under .NET2.0, but that should be irrelevant, any answer is going to involve a p-invoke, I'm sure)

The Windows API calls you will need are: OpenProcess to get a handle to the process (ask for PROCESS_QUERY_INFORMATION rights), OpenProcessToken to get a handle to the process's token (ask for TOKEN_QUERY rights), and GetTokenInformation to get the user account associated with the token (pass TokenUser as the second parameter).
That will get you the user's security identifier (SID). You then need to use the LookupAccountSid API to turn that back into a username and domain.
You can find sample P/Invoke declarations at www.pinvoke.net[^].
