days = (DateTime.Now - anyDate).Days;
If you substract one DateTime object (NOT string) from another DateTime object you get a TimeSpan object. TimeSpan has the property Days which appears to be what you want.

Sir/Madam,
I have two records in my database.From the form , I am chosing the id and want that record to get displayed in the crystal report.There are two tables in the database and there is a primary and foreign key relationship between them.Now the problem is , both the records are comming.I have created links between both tables in the reports.Is there any way to create the crystal report dynalically or can i pass the parameter to show the report.
Parameter means that id which has primary and foreign key relationship.
But I don't know the code how to pass the parameters.
and parameters should be passed at both ends (I mean in the crystal reports as well as on the coding side)??
I don't want to generate the window that ask me which id u want to select .
Please help.
Thanks and regards
Pankaj

I am working at VU meter at the moment. That is, grabbing the microphone volume and show it in progress bar. Should I use winmm.dll for it in vb.net? I understand that I am able to use this module to get output volume but how I should get input volume?
Thanks in advance.

Hi Viewer!
I have a webpage containing a form having a listbox and some buttons. I am faicing the two problems. The first one is that I am facing problem in selecting an item in a listbox form visual basic applicaton.
The second one is that there are several buttons on it having same name. So how can I click on my required button from VB application because there is a confusion that from what name I should call my required button.
Consider it as a CHALLENGE for you...
I have written this because lots of experts are already failed to solve this problem.

You haven't explained the proplem clearly actually.
First Why do you have problems in selecting an item from a listbox? What is the propblem?
Second, each button suppose to have different names inside a form class. Why do they have same names?
What a curious mind needs to discover knowledge is noting else than a pin-hole.

Are you kidding with us or what? Your zip file has an html file. This is a vb.net forum. You should post this under web development.
The text.htm doesn't have the function under scripts. There is no script block and no functions.

You'll have to write that code under Mono, or the Linux's world version of the .NET Framework.

On Windows Vista, Process.Start() generates Win32Exception.
Sample Code:
<br />
Dim selfProc As String = System.Windows.Forms.Application.ExecutablePath<br />
System.Diagnostics.Process.Start(Chr(34) & selfProc & Chr(34)) <br />
The generated Exception:
<br />
System.ComponentModel.Win32Exception: The parameter is incorrect<br />
at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startInfo))<br />
at System.Diagnostics.Process.Start()<br />
at System.Diagnostics.Process.Start(ProcessStartInfo startInfo)<br />
at System.Diagnostics.Process.Start(String fileName)<br />
at ...MyProcedure(...)<br />
What is wrong with my code?
Thanks

Hi
I have been reading up on .Net Remoting for some past days. What I understood was:
1. Create a remotable object.
2. Create a listener referencing that remotable object.
3. Create a client referencing that remotable object.
4. Use config files to indicate where the object resides.
5. Start the listener.
5. Start the client.
To make sure that I was using the server's version of the Remote object, I maintained the interface, but the changed the implementation.
The problem is, it still shows the implementation from the client!
I am using http as the channel, port no=8888
deployed the client exe on a remote machine and gave my machine's url as the remote object location.
What am I doing wrong?

if you are using the System.Windows.Forms.DataGrid..........
don't use it to edit your data because you will suffer, just use
it to view data

You can pick a color for a transparency key for your ENTIRE form, not parts of it. If there is anything painted on your form that is this chosen color, even in a Flash animation, it'll be drawn transparent.
