hi Jshell,
thanks for the reply ,
but in my case o/p is being generated dynamically number of rows or columns generated are totally unknown and most importantly my output (i.e final result ) is being generated by using pivot on n number of rows of a intermediate temp table.

The label won't repaint itself until the code is out of the loop back to the message pump. Then you'll see the last item that was set in the Label control.
The reason is that you have your long running code hogging the UI (startup) thread. This means that the UI cannot get any messages to tell it to repaint controls, including your label.
The solution is to move your long running work to a background thread, BackgroundWorker, or Task. Your background thread code them has to Invoke a method on the UI thread to update the Label control as needed. There are plenty of examples all over the web. You just need to search for "VB.NET BackgroundWorker with progress".

hi,
I am using webbrowser control, my question is:
is possible to suppress dialog box "save as" and download file silently?
thanks erika

No, this would break security, and allow websites to download malicious programs such as viruses etc, without the PC owners' knowledge.

so is it not possible to workaround the problem? can I simulate the user's click sending some command?
|
|
|
|

No, the reason for not allowing this is to prevent malicious use. Why do you want to breach security systems that exist to protect the user?

use HttpRequest or FtpRequest instead of webbrowser control.

I haven't got the url of the file, it is a file dynamically created: when I click a button, the file is created and sent onfly.

You need to compile your app as 32-bits when using the 32-bits libraries, and as 64-bit when using those libraries.
Which did you install?

In VS 2012 Express, I created a solution called syncpro and then renamed it multisyncpro in the solution window by using F2 and renaming the solution and then the project.
I noticed however, in the folder structure
MyDocuments
multisyncpro
syncpro
etc.
that the second-level folder is still called syncpro. In a solution that has not been renamed, the two folders are the same name. If I rename that folder outside of VS the solution won't load. How can I rename this folder so it matches the new name of multisyncpro?
Thanks...

It is a bit of a pain to do this but can be achieved as follows:
- In Solution Explorer, remove the project.
- Close the solution, saving changes
- Go to Windows Explorer and rename the folder containing the project
- Open the solution
- In Solution Explorer, use "Add Existing" and add the project back into the solution.
Use the best guess

I'm developing an application for mobile devices (Windows CE 5.0, .NET compact framwork 2.0 pre-installed) using .NET compact framework 3.5 and MS Visual Studio 2008.
I'm using the built-in option for creating localized forms. This works perfectly as long as I use the debugging function of Visual Studio with the mobile device connected to my desktop computer. In this case, Visual Studio deploys my application along with .NET compact framework 3.5. After disconnecting the mobile device and having installed my application it is still working as expected.
My problem is: If I install the .NET compact framework using the CAB file provided by Microsoft and then install my application (also by using the CAB file created by Visual Studio) without having used the debugger the application works as well but without localization. So I think there must be some parts of the .NET framework which are only installed using the deployment function of Visual Studio. - Does anybody know which parts (libraries...?) these are? Since the application will be provided to users which will not use Visual Studio I've to find a solution for this.

Hi,
I have an windows application. On button click, I call a service called ServiceA (ServiceA is in my local machine). From ServiceA's method, I hit database and retrieve some records. After retrieved, I call another WCF service called ServiceB (ServiceB is availabled in another machine within network). I have added ServiceB's proxy files in my ServiceA's project. endpoints and bindings are added in wwwroot\web.config. When I try to consume ServiceB's method, I am getting the following error.
Could not connect to http://tde017:8080/AdapterService/AdapterService.svc. TCP error code 10013: An attempt was made to access a socket in a way forbidden by its access permissions 17.21.11.17:8080
Previously, it throws with the port number 80. I configured the another port 8080. Now error is throwing with 8080.
But, If I consume the serviceB directly from my windows application, I am getting response. If I go through another service, I am getting error.
I tried many scenarios. But, still I could not get solution. Any one help me on this....
Thanks in advance.
Regards,
Bala
