If Form1 is your main form and Form2 is your subform, on the button click event write
Form2 f = new Form2();<br />
f.Show();<br />
this.Hide();
Although we should remove memory use for Form1 but I dont know how too

Look for the static Main method of your application. If you created your project with VS2005 its in a separate class called Program otherwise it's in the first form created. There you find the following line of code (the name of the form class may be another):
Application.Run(new Form1()); If you want another starting form simply change the type of the instance that gets created and then passed to Application.Run.

You can find the following code in the main.
Application.Run(new Form1());
If you want to run the form2 then simply change this to
Application.Run(new Form2());
My small attempt...

Hi,
I am working with C# and Crystal reports 10 and C# 1.1 VS 2003. When I run my project i get following error:
"A Crystal Reports job failed because a free license could not be obtained in the time allocated. More licenses can be purchased direct from Crystal Decisions or through the Crystal Decisions Online Store."
Also I have another project which is working fine with the same things, so I think license for Crystal reports exists, and this is some thing else.
Also sorry if this is not the right place to post this question.

There are several ways to do this.
One easy way is to write it to windows log entry using the EventLog class. In the service you'll create a source with your service's name, and in the Stop() method of the service, you write an entry to the Log. In the applications use the same class to monitor that log. When an entry is written an event called EntryWritten will be raised.
PS.
This may not work when you service has been forcibly ended using the task manager.

I am displaying records from an MS Access Database. One of the fields is the person's marital status. To conserve on space, I have saved it as a short Int: 0=Unknown, 1=Single, 2=Married...etc. What I'm trying to do is convert that numeric value to the textual value when it is displayed in the DatagridView. I am toying around with some ideas but they all seem too time consuming. Does anyone have any ideas on how to go about this?

hi,
I have idea like this. In design mode, you add column collection in datagridview. With material status column, you do choose DataGridViewComboBoxColumn with items (0 - Unknown, 1 - Single, ...).
You must add each record in MSAccess into datagridview in code. That's all.
hope my help.
P/S: I'm not sure we can do your idea.

|

|

Thanks for the information. I was thinking about creating a column like that with code. One thing that seems too time consuming is looping through all the records to set the appropriate value. Do you know if the DataGridView has a way to trap the event of a row being created? That way the cpu wouldn't have to do double work.
Thanks again for the help.

Hi All:
I have the following algebraic equations I want to code in C#. I am not sure how to do this. Please help!
495 = 66t + c
951 = 190 + c
How do I write this in code?
Thanks,
Laura

Sorry the equations are actually:
495 = 66t + c
951 = 190t + c
Thanks! Please Help!

Are you looking for an algorithm for solving two simultaneous equations[^]? And you want to code that in C#?
Make sure you understand the algorithm first without being concerned about how to implement it in C#. Once you have a strong handle on the algorithm, you can then begin to consider how to implement it in C#. The above link describes three approaches.
