Hi All,
Kindly let me know the method, How to Maximize loaded program.
Example:
--------
Only Notepad is running on my system which is already minimized on the tray, and I want to maximize it using C# code.
Thank you

You need to p/invoke some windows api to achieve this. First you need to get the handle of the window that should be maximized and then use that hahndle to maximize it. Take a look at this these on pinvoke.net:
FindWindow (user32)[^]
ShowWindow (user32)[^]

Hi,
I'm trying to use the Conditional Operator in C# in the form of
<bool condition> ? <true value> : <false value>;
and I want the value to return as NULL if the condition is false.
For example:
bool _validated = _boolText != null? bool.Parse(_boolText): null;
But an error occurs when trying to build.
Here is the error message:
Type of conditional expression cannot be determined because there is no implicit conversion between 'bool' and '<null>'
How can I solve this problem?
Thank you very much.

You must declare your boolean type variable to a nullable boolean, but this will only works in .NET 2005.
bool? _validated = _boolText != null ? bool.Parse(_boolText): null;
If you want to declare a nullable bool just add suffix "?" symbol to your datatype.
ex.
bool?
int?
string?

Wow! Thanx a lot, Mark.
Never known there is this trick in C# 2.0.
By the way, is there any way to convert from non-nullable to nullable?
Say... I need to assign a value to a variable for web service.
In my provided example, the variable for a web service is of bool type.
How can i convert it to "bool?" ?
Thank you very much.

The non-nullable bool have two posible values either True or false only. I think It's imposible that your web services will return a null value if does this will generate an error object not set to instance. Back to your question. Yes, you can, just cast it.
bool? myvar = (bool?)MyWebServiceMethodBool();
Note: MyWebServiceMethodBool() will only return True or false because the data type of this method is non-nullable boolean the only posible value this method will return is either true or false.
the new myvar variable can have three value (true,false and null)
regards,
Mark

hi all,
I am using a webbrowser control in my application.I have a menu which can open or save files displayed in the browser.I am able to open all office documents and text files in the browser.
Also i am able to edit the office documents and make changes and also able to save them.But when i open a text file in the browser, i am not able to edit the text in the browser.
Can anybody suggest me how to do this?
Thanks in advance.
Regards
Anuradha

Hi,
I think that you can't edit a simple txt file in the browser because the browser only shows its content. When you open office documents, the browser opens the files inside the browser with the properly app, but in the case of the txt file only reads its content and shows it.
An alternative solution is that you add a button that open a dialog form that let the user edit the text in a richtextbox...

hi,
Thanks for the response.I think you are right. The normal browser opens all the text files as well as the office documents in a separate file and makes them editable.
Maybe i should try for that.
Thanks for your help anyway..
Thanks in advance.

I am looking for a C# WPF carousel project, but so far I was not able to find any that works.
The effect must be similar to those that can be done with flash or to this screen shot:

I'm looking for some good starting points for creating a call center utilizing VOIP.
Basically, I need to somehow accept incoming phone calls, present the customer with a brief automated message, and then transfer them to an available rep.
The catch however is the reps are not all within the same location. The reps answer phone calls from their home computer.
I was originally looking into TAPI 3.0 but since I'm looking to transfer calls via VOIP, I don't think this is a viable option.
Does anyone know of some good tutorials on this or know of some (modifiable) software that can handle this?
Thanks.

I am having trouble getting a regular expression to match a dollar value. The string I'm using is:
\b\$35,000\b
If I remove the \$ then it matches the 35,000 string, so I am guessing I must be doing something wrong.

I think this will match US currency for you.
^\$(?:\d{1,3}(?:\,\d{3})*|(?:\d+))(?:\.\d{2})?$
