how to refresh DataGridView MDI Application

GetFree123GetFree1-Mar-06 19:16

Hi,
i have a MDI application with MainForm (MdiContainer) and a ChildForm, MainForm has a text box and when user enters some text and clicks search button

i have the following Click event so that i show the results in ChildForm

1) ChildForm _cf=new ChildForm(string CustName);
2) LaunchChildForm(_cf);

1) ChildForm(string CustName) is a constuctor on the ChildForm that does the customer search and sets the datasource of the dataGridView....something like...

_results ....;
dataGridView1.DataSource = _results;

2) so that it only shows one instance of the Child From.

My Question is it only works for the first time, but it doesnt work when i do the search again, seems like it does not refresh the dataGridView?

is there anything i can do?
Thanks

How can you determine at run time in C# if you're running on a 32 or 64 bit machine

Hello Jared,

I am not sure about this method. Becoz i have no PC of 64 bit. But you just try.

Check size of 'int'. like

val = sizeof(int);

if it is 4 byte then 32 bit machine & if 8 byte then 64 bit machine. For my 32 bit machine it is 4.

That doesn't work in C# because int is guaranteed to be 4 bytes regardless of the architecture.

Values are the same size for both 32 and 64-bit (an int is 4 bytes on both.)

I don't believe there is a simple, standard way to detect this.

Hello Joe,

Sorry for my answer. But i think that int data type is for best CPU performance. And for fix length type you have to take long & short.

The int data type is just an alias for System.Int32. A long is System.Int64 and short is System.Int16.

Yes, you are of course right, in the same way as pigs can fly. If the pig is a bird, it can fly. This will of course not work if the pig is a pig. Wink | ;)

Or better yet

IntPtr.Size.

That looks like the right approach though. Thanks!

You can use

val = IntPtr.size

But it will give bit of platform not a machine. Which is some time difference.

Hi
I presume you have a 32-bit assembly and want to know if you are running on a native 32-bit machine or under WOW64 on a native 64-bit machine.

There is an API method IsWow64Process you can call using pinvoke - I could not find a managed method.

Jeyakumar,

SaveFileDialog should validate those stuff right?

If you still like to query Path.InvalidPathChars should contain an array of prohibited characters.

Progress Percent of SMTP Client

Nadia Monalisa1-Mar-06 18:09

1-Mar-06 18:09

Hi,
I am Developing for .NET 2.0 C# Express 2005 Windows Application.

I tried to implement progress bar for SMTP email sending,

SmtpClient client = new SmtpClient(smtpServerName);
try
{
client.Timeout = timeOutSmtp;
client.Send(message);
}
catch (Exception err)
{

}

But I did not find any way to know how much percent of byte has been sent out of total bytes. I searched in MSDN and found, Socket class has this feature ( percent of byte sent ) but I am kind of new and I am not familiar with Socket TCP/IP etc. So, is it not possible to know the percentage of sent bytes for this SMTP client ?

Thanks and appreciation in advance.

C# VS2005 - Installing deployed application to an specific path

Hello everyone,

Where exactly do I configure a C# application to install in a specific path? Like, for example:

C:\Program Files\myApp

Please note that I don't mean the deployment folder!

I looked throughout the application properties, publish properties and publish Wizard, but didn't find a configuration option for that.

Thanks a lot,

C# VS 2005 - Crystal reports question

Hello to all,

When I'm running my application from the debug folder, I'm able to save changes to the database, but when I load the Crystal report to display that data, it still displays the old data, i.e., the data before the changes.

Does it have anything to do with the database Build Action property and Copy property or it has something to do with the report source path?

Thanks a lot,

JC.
