If the GUI thread is doing lots of work, your GUI might not get repainted, especially on slower machines.
To make sure your GUI gets updated, you can make a call to Application.DoEvents, or you could use a 2nd thread to do the heavy work, and use the GUI thread only to update the progress bar.
You can also force a control to repaint itself using control.Update().

hi
I need some help.
I do trading on an exchange like a stock exchange.
I have to send http:// string to a server, in the string I can set the properties what i will do for example
http://Mybroker.com?buy?something?10K
http://Mybroker.com?cancel?all
http://Mybroker.com?sell?someotherstuff?20K
I have this strings stored into a file called multiorder.txt
So I have developed a c# program to read out this multiorder.txt whenever the file is changed.
Then I will send this lines via http.
I use multithreading to send up to 20 hrefs at the time but my problem is that only 3 or 4 of this will be send all the other lines will not send. I get the error message, that there are problems with the internet.
To send one line wait till response from the server and then send the next one will take to much time as the XML request I get takes about 40 seconds.
I need simply an idea how i can handle it to send 30 hrefs through .net at a time without crashing the program.
Thanks for help.

This seems really an inefficient way. If you're making 30 requests to a single webpage simultaneously, you're bound to run into problems. A better way would be to concat the different href commands together into a single command (provided the server can understand that). So your string would look like http://mybroker.com?cancel?all;buy?something?10k;sell?someotherstuff?20k
That said, what is the exact error you're getting?

hi all,
i have a small doubt, which kicking me back to somewhere. i am using and used lot of custom dlls on my projects which i will be transport with .exe file on delivery time. Now, i am using Sybase database in one of my project. Here i am using Managed provider for Sybase data accessing. iAnywhere.Data.AsaClient is the name of managed provider which use to access Sybase database.
When i try to export and try to install my application on some other machine , it is installing properly and i can see iAnywhere.Data.AsaClient is also exported with my .exe file.
Here the problem start, when i start running the application, it is not connecting to the Sybase database even though iAnywhere.Data.AsaClient is available .
If i want to run my application, i need to install Sybase (Only the provider) in that machine.
I think my application is not referring IAnywhere.Data.Client from its installed directory. And application is working fine, if i install iAnywhere.Data.AsaClient in GAC where i installed my application. But this will won't serve my purpose. And i can't rely on users or implementation people to get it done.
Any idea which will help me to get out of this Sybase installation will be most appreciated.;)

Is the DLL in the application directory, or one of its subdirectories? If it's not, then the CLR has no way of knowing where it is, unless you point it to a specific location in the configuration file. Because the GAC is a standard location known to the CLR, it'll be able to pick DLL's loaded there by itself.

Yes, Dll is in the application directory.
You wrote:

I am not talking abt or least bothered abt GAC. I just wrote to inform the thread submitters that , i don't want to play with GAC. To be simple, i can't able to tell the user or Implimentation guys to try with GAC.
What i need is, it need to work IAnywhere.Data.AsaClient like other custom dlls, which we using some or all applications.
Any Idea ?

It is not connecting? Whats the error message? What kind of exception is raised? Where is it raised?
The only hint I can give you without any futher info is, that you should check that not only the 'iAnywhere.Data.AsaClient.dll' is present but also 'dbdata9.dll', which is also needed.

Little more clear please...
I am getting an error message says, Unable to connect to Ianywhere.Data.Asaclient. The moment i install Sybase to that computer, my application won't show any error message and will work smoothly.
Anyhow what is that 'dbdata9.dll'. Where i will get this ? What is the realt use of that file ?
What is the important of that .dll in my application ? Give me some more idea .

I tried the way you told. But i can't convert that dbdata8.dll valid assembly.
The error which i am getting is , it is not a valid library or Com.
Please help to come out from this issue.

Have a look at this. Its not particulary for the .Net client but it surely gives some hints.
In Chapter 16 is explained what deployment options you have. After reading some parts of it I would either suggest the silent install or (a bit more professional) the merge module. Merge modules can easily be integrated in Visual Studio generated setups (just by right clicking on the setup project and selecting add->mergemodule).
edit: Merge modules end with .MSM. If you do not find the appropriate merge module fpr the AsaClient in the normal app path then have a look at Program Files\Common Files\Merge Modules.

I have a small printing application (using PrintDocument class).
I have several Printer Drivers installed on my comp, but when I physically disconnect any printer and try to Print anything, the application abruptly terminates.
Can any one guide please?

Use proper error handling mechanisum (try...catch) to identify the error type and source.
And check whether your printing logic will take any default printer or networke printer to print the required page.;)

I have a problem with registering my software, but i don't know how to security my trial version. Can everybody help me?
Đào Ngọc Hào! Hi How Are You?

Little confused.
If you want to run your application as a Trail version , then you need to add some logic in your source itself to check the license or validity.

Hi Thank you for your answer!
But just more somethings I don't understand. If someone decompile my main application and view the directory where contains registry information. Then That's it. Is there any solution for this.
Đào Ngọc Hào! Hi How Are You?

You might try storing an encrypted date (or some other data to identify your program as a trial version) in the Windows registry. But don't put it in an obvious place and call it by an obvious name. This way it is not as easy to beat. Be careful in the Windows registry, because you could mess up a program (even Windows itself) and have to reinstall the program.
If you don't know anything about encryption, try searching for it here. There are several ideas about encryption out there that will help you.
