In C# you cannot assign a string to int. Try-
int s=Int32.Parse(cm.ExecuteScalar());
CAUTION : What if your database has a null value or some string value in the field being retrieved ? This would raise an exception in the Parse method. The best practice is to use exception handling and checking whether the returned values are not null. Also apply proper constraints on the database to avoid these kind of errors.

it gives error : Cannot implicitly convert type 'string' to 'int'.
If you want to put the return value into a integer variable, why do you convert it to a string.? Cast the return value of ExecuteScalar to int directly.

This is because you had error on the initialization of that int. correct it and this error will be gone.

how can i open(visualize) a System.Windows.Forms.MenuItem of System.Windows.Forms.MainMenu by code?
Maybe one could disassemble the ToolStripMenuItem and see what they are doing inside the ShowDropDown method. Or use Windows API to really simulate a mouse click on the menu item.
how can i do this?

You could do it yourself. The MSIL Disassembler-Tool (Ildasm.exe) is part of the Framework SDK. Information on its usage can be found on MSDN.

You mean while installing the application? Haven't the user informed the path he wanted to install the application to?
Otherwise the program itself knows its path by using this variable:
Application.StartupPath

Hello,

Maybe you should take a look at WMI and what it can offer in terms of retrieving the installation path of a software installed on a machine.

My application is in C# and it runs on a mobile device(its a Symbol device). I want to start an exe in the '\Program Files' folder from my application. Can anyone tell me what command (line of code) to use..
I see that for playing .wav files there is 'Symbol.Audio.Controller' , is there any such thing for exe files.

Hello,
in the namespace "System.Diagnostics" you will find "Process" and "ProcessStartInfo" class.
Like:
using System.Diagnostics;
ProcessStartInfo PSIYourProc = new ProcessStartInfo();
StartLoader.UseShellExecute = false;
StartLoader.WorkingDirectory = @"C:\...";
StartLoader.FileName = @"C:\...\xxx.exe";
Process PYourProc = Process.Start(PSIYourProc);
//Don't forget to dispose the Process if you don't need it anymore!
All the best
Martin

I included 'using System.Diagnostics;' in my headers. But I see that "Process" and "ProcessStartInfo" classes are not available for me in "System.Diagnostics".
Is there something else required ?
The classes I am seeing in "System.Diagnostics" are
- ConditionalAttribute;
- Debug;
- DebuggableAttribute;
- Debugger;
- DebuggerStepThroughAttribute;
- DefaultTraceListener;
- Trace;
- TraceListener;
- TraceListenerCollection;

Which version of the framework and OS are you using?
|
|
|
|
|
I am using
Microsoft .NET framework 1.1 (Version 1.1.4322 SP1) on a Windows XP system
OS Version on Mobile device is 05.01.0070

|

Try to find System.Diagnostics.dll in the .Net references for the project and give a reference to the same. I think that must be your problem.

I'm trying to have two related tables appear in one datagridview with the ability to update/insert/delete. Here is a simplified version of what the table structure looks like:
Table1: Table1_ID, Order_No
Table2: Table2_ID, Part_No, Table1_ID
I have shown in datagridview: Order_No, and Part_No
But i m unable to update/insert.
Any body have idea how update/insert operation works when data is coming from two tables.
I am using visual studio 2005 / C#

Hi all,
I'm stuck. Please help me.
I'm would like to be able to change the Internet Explorer Security settings/options from my own C# application. Because my browser object seems to use the settings from Internet Explorer. Not sure if they can be separate or not (meaning for the browser object in my own application to have it's own setting)? Is doable? I've heard you do it through the registry, but all the info out there is very limited and I'm new to this.
Please if you can give me a sample code at least to point me in the right direction.
I would like to be able to specifically change the ActiveX setting Enable/Disable, and the JavaScript one.
Thanks SO MUCH!

These are set for all instances of IE. I don't know how to set them outside of IE, but I'd hope that it's hard. I mean, that's kind of nasty, don't you think ?

You and every virus writer on the planet. This would represent a major security hole, and is not allowed from an embedded control.
the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer
Deja View - the feeling that you've seen this post before.

Wow...that's such a simple thing and noone here know how to do it.
All the security settings are in the registry, I don't see why it would be so hard for someone who knows. I think those webBrowser objects are useless if you can't change the settings of your own browswer object, from your own app. Come on guys that's ridiculous. Can a sound programmer please answer my question.
