I have listview (left side) in the screen and right side 3 radio buttons.
I Want to implement in .Net windows application using C#.net (2.o framwork).
LIst view nodes are fixed. When I open any root nodes it should display the child nodes and at the same time, i need to display the the 3 radiobuttons for each child node. When I collapse the root node then child nodes should collapse as well as the radio button should not be displayed.
eg:
Fruites
---> Mango Radio button1 Radio Button 2 Radio Button3
---> Apple Radio button1 Radio Button 2 Radio Button3
Vegetables
---> Tomoto Radio button1 Radio Button 2 Radio Button3
Can any one give me some hint to implement this.
thanks in advance

Hi every body,
I am getting a problem when i work with Microsoft.Interop.Excel.dll
I tried to export and modify excel file with my conditional formatting for each cell of rows.
the function is :
Microsoft.Office.Interop.Excel.Range cellitem;
cellitem.FormatConditions[1].Modify(XlFormatConditionType.xlExpression, XlFormatConditionOperator.xlEqual, "=AND($X$" + position + ">2,MOD($X$" + position + ",2)=0)", "");
it was working good in English region but when i changed the region to Germany(de) it was crashed.
I don't know what is wrong .
Could you help me any solutions!
Thanks,

Try to use "," instead of "." in float number.

hi,
Thanks for your answer, but I'm sorry, I don't understand your answer.
Maybe you thought that the formula contained a float number. Unfortunately, it does not contain any float number. I tried to modify a simple formula but it still does not work well when changing to German region.
I updated the example that I did for clearer question.
I really appreciate if someone can help me this urgent issue.
Thanks.

I don't know about the formula. But English Excel has some differences with German Excel.
For example, if you want to count the average, in german excel you must use:
=MITTELWERT(...)

hi stancrm,
 Thanks a lot, I have finished solving my problem.
From your ideal I have changed the format of formula input because in German the ',' is changed to ';'.
Now it works well.
One again thanks to you .
I posts the change here to any one can compare and understand clear about the problem if they have.
cellitem.FormatConditions[1].Modify(XlFormatConditionType.xlExpression, XlFormatConditionOperator.xlEqual,
"=AND($X$" + position + ">2;MOD($X$" + position + ";2)=0)", "");

Best bet is to contact the developer at sourceforge.

Hey, I was writing some code for my class and the assignment is to create a domain model and then also make an xml document of the information. I have been getting the following error

I checked through the inner exception and found that im getting a circular reference error and when i checked on boards and also other articles I found that basically its because i can't use a circular reference. Im having a hard time understanding this and was hoping that i could get an answer to how this can occur.
Thank you.

The built-in XML serialization is evil and should be avoided; always write custom serialization.
Having said that, and not wanting to read too much of what you posted, I can only guess that a Customer has a Vehicle and that Vehicle has the Customer and that is the circularity. How you remedy that (with the built-in XML serialization) I don't know, but once you figure it out you should have learned something.
"We learn more from our mistakes than we do from getting it right the first time."

Thank you for the advice and explaining how this is probably happening. I do have the customer in vehicle even though I don't want that. I will keep going through the code and hopefully I can figure it out.
For right now I would rather use the built-in stuff since im not entirely familiar with writing custom serialization.
Again thank you and I will post on what I did after i figure it out.

Thank you for your help. I figured the problem out and you were right. I was calling the customer class in vehicle and then using this in my test model. This was kinda, for lack of a better term, circular. Once i fixed this up, my code worked great.
Thank you again.

Don't get me wrong, it might make sense to have the circularity in the data. You just might not want to do a very deep serialization. And I don't know enough about the built-in serialization to say how to do a shallow serialization (if that's even a proper term).

hello friends,
How can I have my command prompt in the programming?
for example I want to write "attrib +h +s [address]" and run the attrib.exe in my program procedure (with the arguments (+h and +s)) and see the output lines if any.
how is that?
thanks
|
|
|
|

You can use Process class to start attrib.exe with the parameters you need. You can also redirect standard input and output to read/write input/output. A simple google search will bring many examples.
Have a look at this too: Command Prompt Control[^]

Have you seen the sample code in the SslStream Class documentation[^]?
There's both server and client code there - may be helpful ...

Hi!
I have search for hours after a good guide to create, edit, save and load a Excel file in C#. Those I have found does not work!
