Use int.TryParse() method.
string str = "123";
nt num;
if( int.TryParse( str, out num))
{
}

I think Regex would be the way to go:
return Regex.IsMatch(yourText, "^\d+$");
This would work for simple numbers.

I am creating a 5 star rating control. For this I have created a user control with the Callback functionality. When I implement the usercontrol on an aspx page, I want that the label control to populate the value of the image that was clicked. But, when I debug my application, it shows that the label control has the value and it does not show on the page. Following is the code I am using for the User Control:
public event System.Web.UI.WebControls.CommandEventHandler Rater;
protected void Page_Load(object sender, EventArgs e)
{
sCallBackFunctionInvocation = Page.ClientScript.GetCallbackEventReference(this, "message", "ShowSuccess",
"context");
String callbackScript;
callbackScript = "function CallServer(message, context)" +
"{ " + sCallBackFunctionInvocation + ";}";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(),
"CallServer", callbackScript, true);
}
public void RaiseCallbackEvent(string eventArgument)
{
if (hdn.Value.ToString() == "" && (eventArgument == "0" || eventArgument == string.Empty))
{
returnValue = "0";
totChecked = returnValue;
hdn.Value = returnValue;
}
else
{
returnValue = eventArgument;
hdn.Value = returnValue;
totChecked = returnValue;
CommandEventArgs args = new CommandEventArgs("Rated", hdn.Value.ToString());
Rater(this, args);
}
}
public string GetCallbackResult()
{
return returnValue;
}
The following code is used for aspx page
protected void Page_Load(object sender, EventArgs e)
{
rc1.Rater += new CommandEventHandler(rc_Rater);
}
private void rc_Rater(object sender, CommandEventArgs e)
{
RatingControl rc = new RatingControl();
lbl.Text = e.CommandArgument.ToString();
}

Probably best to ask this in the ASP[^] forum.

Hi,
I have developed a windows sservice on my dev machine.
The project installer is also created.
This service is tested on my machine and it is fine.
Now I would like to give it to the management to install/run it on the required machine.
Question:
How should this windows service application be setup on the requred machine which may or may not have .net framework?
Thanks
|
|
|
|
|
if(!TargetMachineHasDotNetFramework)
{
InstallRequiredDotNetFramework();
}
InstallWindowsService();
well, you did ask in the C# forum.
|
|
|
|
|
I think you mis-understood.
I would like to know how to install the windows service on another machine? I mean do I just copy the whole development codes to the other machine, etc?
Thanks
|
|
|
|
|
You said you had an installer for your service, wouldn't logic tell you to install your service you would use the installer?
|
|
|
|
|
On my machine which has visual studio, I run the vs command to install or un-install the service.
The question is:
What do I do if this service needs to be installed on another machine? If the installer is required for this purpose, then how do I run it on another machine. I believe I can not get vs command on the other machine.
Hope you follow my question.
Thanks

Easiest way is to create an installer, take that installer to the other machine and run it.
A Google search[^] will provide you with a plethora of information on the subject.

To install the Windows Service on another machine you would add a
Setup project to your solution which would then create an MSI package.
Run the MSI package on the target machine and this will create the Windows Service.
Obviously you would need the relevant .NET Framework version on the target machine.

|
|
|
|
Can I do this by the click once method to install the service on another machine?
Thanks
|
|
|
|

I highly doubt ClickOnce will work for services

Hi,
How can i save value from textbox into database
or change some value in database with value in textbox.

Read some books/tutorials, your question is so vague, I assume you are a beginner. You will need some background knowlegde on the process, but once you do, you will find it is trivial

Hi Guys,
I have one batch file. I set argument in it and when I double click the bat file,it work perfectly . Argument only suggest to execute other SSIS packages on a given path.
Argument is:
FOR %%V IN (*.dtsx) DO dtexec /f "%%V" /Config "cfg%%~nV.dtsConfig" >> log_PkgExecution.txt
pause
Now, I want to set the same argument in SSIS Package called "Execute Process Task" in Execute Process Task editor -> Argument property. I did it, but getting problem during execution.
On executing the package, DOS prompt is coming blank...
I think, it is not getting the argument...
Please help, if I am doing something wrong.
Thanks in advance.

It will be. You are redirecting output to the log_PkgExecution.txt file. Have a look in there.
Your question is also not C# related.

I couldn't see the rows affected in my DB by packages which are executed by this bat file...In short, this batch file is not executing the argument.

Hello everyone,
When using !threads command to monitor thread status for a dump, there is an error message. Does anyone meet this before? What is wrong?
0:001> !threads
Failed to load data access DLL, 0x80004005
Verify that 1) you have a recent build of the debugger (6.2.14 or newer)
2) the file mscordacwks.dll that matches your version of mscorwks.dll is
in the version directory
3) or, if you are debugging a dump file, verify that the file
mscordacwks_<arch>_<arch>_<version>.dll is on your symbol path.
4) you are debugging on the same architecture as the dump file.
For example, an IA64 dump file must be debugged on an IA64
machine.
You can also run the debugger command .cordll to control the debugger's
load of mscordacwks.dll. .cordll -ve -u -l will do a verbose reload.
If that succeeds, the SOS command should work on retry.
If you are debugging a minidump, you need to make sure that your executable
path is pointing to mscorwks.dll as well.
thanks in advance,
George
