The only way that I can think of is to write yet another program that should be started when the user clicks on it. That new application would then start the selected installer with the Process.Start() method.

Thanks Mr.Thomas for the suggestion...

But I think there should be some other better option to do this...

That is the only option that I can think of with the out-of-the-box visual studio. The only other option that I can think of is to buy a third party installer creation suite.

openFileDialog win form

Hello,
The following code shows how to use the openFileDialog to read the contents of a .csv file into a textbox.

Question:
After selecting the file iin the dialog, how do I actually open the file?
remember that I would like to open the .csv file and NOT read it into the textbox.

StreamReader ts = null;

openFileDialog1.CheckFileExists = true;
openFileDialog1.CheckPathExists = true;
openFileDialog1.DefaultExt = "csv";

openFileDialog1.Filter = "Text files (*.csv)|*.csv|" + "All files|*.*";
openFileDialog1.Multiselect = false;
openFileDialog1.FilterIndex = 2;
openFileDialog1.ValidateNames = true;

if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
ts = new StreamReader(openFileDialog1.OpenFile());

txtSQL.Text = ts.ReadToEnd();
}
}

Thanks

Hi,
As I mentioned in the first post, please note that I would like to actually open the file rather than reading it into the textbox.
Like as if you double click the file and the .csv file opens.
Thanks

What the other person suggested is what you are trying to get to. By creating a new stream you are opening the file (or as close as you can get to it in C#). You can then manipulate what the stream returns before you put it into the textbox.

define status bar panel...

if you want to draw custom stuff on a control such as the panel youd use its OnPaint event handler like so

OnPaint(object sender, EventArgs e)
{
    // This will draw a line from the 1st point(x = 50, y = 50), to the 2nd point(x = 100, y = 100) 
    e.Graphics.DrawLine(new Point(50, 50),new Point(100, 100));
}

look around in the graphics object to see what else you can draw

You need to create a class that inherits from the status bar panel, and then alter its painting methods.

Printer service using c#.net

Hi,

Iam developing an application using c#.net for printers. My requirement is as follows

1. when user opens a file(say an example sample.doc)in that document he may select the Print option then Print dialogue box opens,and if he selects the printer in the specified network then the selected file(as in our example sample.doc) should not go to the windows print spooler..it should go the specified location(this location i will keep in my code).

I came to know that this can be done by using WindowsAPI.But to accomplish this I need all of ur guidence.

One more clarification I needed is that there is any possibility to run my service on print command by stoping the default service on that print command.

I have to do this without any client application.

Iam reuqesting all to help me...

You can use the PrinterSettings[^] property to check the printer name that the user selected.

PrintDialog pd = new PrintDialog();

if (pd.ShowDialog() == DialogResult.OK)
{
    if (pd.PrinterSettings.PrinterName == @"\\unc-path\myPrinter\")
    {
        pd.PrinterSettings.PrinterName == @"\\new-unc-path\newPrinter";
    }
}

are you doing a WinForms project?

if you are i think you want MDI windows....

to do that set the window you want to contain all the other windows MdiContainer property to true. Then When you create the child form set its MdiParent property to the instance of the parent.

buttonOneClick(object sender. EventArgs e)
{
    MyChildForm myChildForm = new MyChildForm();
    myChildForm.MdiParent = this; // assuming you want the child form to be inside the form your calling it from
    myChildForm.Show();
}

yes use MDI like said before. Download some samples/articles here in codeproject and give it a try.

You should try also design usercontrols, and place then inside your form.
Preventing/Instead of creating many forms, you can create many usercontrols and display/load then in the same form.
I think you are going to use this more often.

I have a datetimepicker in my device application(Compact framework). I have put a textbox.I am not able to show today's date in textbox by selecting today's date in datetimepicker. I used the event selectedvaluechanged of datetimepicker. I need to show any other date and then only i am able to show today's date

Either select a different value for it's initial value or after setting the date call the ValueChanged method manually.

dateTimePicker1_ValueChanged(this, EventArgs.Empty);

Language encoding problem

27-Jul-08 23:12

Hi,
Why do I get these funny little squares when I read Arabic data from my database??
I'm using Oracle 10g and it's working quite fine with any language "I can save it and view it correctly using Oracle sql*plus" but it gets encrypted on my window form...

Please help.

Maybe the control which shows your data has a font selected which does not contain Arabic characters. Often the default font is MS Sans Serif, and this lacks many characters. If you change the font to Arial, Tahoma, Courier New or something you should see your data.

Thanks Frank, but no,
I actually tried many fonts including Tahoma and Airal and even Arabic fonts and set the script to Arabic for this control "it's a tree view".. I thought it was as easy as this but no..

Thanks anyways Frank!

If it's not the font, it must be lost somewhere else. Do you fill your tree view with self made code or do you use some sort of data binding? And do you read from the database with a plain data reader or do you use a data adapter plus dataset? Does your connection string contain anything that might enforce a certain codepage? In my experience (though not with Oracle but only with MS SQLServer) using the Visual Studio designer to define connections, datasets and things often leads to strange results

Maybe you can debug or write to the console (or a log file) what characters you actually get in which layer. Or just set up a tiny test application which just connects, reads a string from the table and writes it to the console.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
