Hi!
The SelectionChanged event is raised when a datagridview is constructed, when the datasource is assigned. How can I avoid that my actions in the event handler are only applied when the user changes the selection?

Thanks for suggestions

Jörg

Are you saying you only want to do something when the user clicks on a different row from the one that he's currently selected? You might want to look here[^] for a tip.

The easiest way is the HTML accesskey[^] attribute.

Either put a Label with the according shortcut in front of your TextBox (with respect to tab order) or set KeyPreview to true for the Form and handle key presses yourself.
In that case you can use the TextBox.Select() method.

Ok, now i've tried this:

        private void VSAddressRegisterForm_KeyPress(object sender, KeyPressEventArgs e)<br />
        {<br />
            Keyboard keyboard = new Keyboard();<br />
            if (keyboard.AltKeyDown && e.KeyChar.Equals('d'))<br />
            {<br />
                e.Handled = true;<br />
                textBoxName.SelectAll();<br />
            }<br />
<br />
        }

... but when I use the <alt>-key my Forms parents main-menue got focus Frown | :-(

Just use the first suggestion: Put a label next to your TextBox, set its Text to something containing "&d" (A&ddress) and assign the tab order to all controls on your form in a way that the label is immediately in front of the textbox.
No additional programming required - works every time.

Oh, and by the way (although I didn't actually try your code) - why are your creating a new Keyboard object? Have you taken a look at the KeyPressEventArgs? They contain everything you need...

Hi,

Someone asked me to help him with the following piece of software, and I don't know even where to start looking. Will this be a big project?

We’re busy with a project developing a website, the background is the tricky part. We’re supplying a scanner that will scan to a FTP site. That part is the easy one, it can scan in pdf and jpg format. The delivery notes they’re scanning will have barcodes on, we need software to read the barcodes and rename the file names according to the codes.

Regards
ma se

Hi I am trying to get an image from a resource file into a picturebox.
using the following code:

using System;<br />
using System.Collections.Generic;<br />
using System.ComponentModel;<br />
using System.Data;<br />
using System.Drawing;<br />
using System.Text;<br />
using System.Windows.Forms;<br />
using System.Reflection;<br />
using System.Resources;<br />
<br />
namespace WindowsApplication16<br />
{<br />
    public partial class Form1 : Form<br />
    {<br />
        public Form1()<br />
        {<br />
            InitializeComponent();<br />
        }<br />
<br />
        private void button1_Click(object sender, EventArgs e)<br />
        {<br />
            Assembly Massem;<br />
            Image Mimage;<br />
            Massem = this.GetType().Assembly;<br />
            ResourceManager RM = new ResourceManager("WindowsApplication16.PH1", Massem);<br />
            Mimage = (Image)RM.GetObject("MIS_1.png");<br />
            pictureBox1.Image = Mimage;<br />
<br />
        }<br />
    }<br />
}

the form has 1 button & 1 picture box.
Resource name is : PH1.resx - inside there is the image file .

Hi!
You have to take care to use the correct name for the resource. Usually you have to prefix the object's filename with the namespace of your application (e.g. "WindowsApplication16.MIS_1.png" or whatever your namespace is).

Hi,

I cant remember all the details, so this is what I do:

- add the image file to the project, set it to "embedded resource"
(you probably did that already)
- use Designer to add some control (say picturebox) that consumes an image,
and set it up to use your image
- now look at the code Designer has generated for you, and copy/paste what you need
- throw away what you no longer need

Works the first time every time.

Smile | :)

File Conversion from CSV format Excel format in C# [modified]

liyakhat_shahid10-Jul-07 3:00

Hi,

I have created a class. In that I have written the following code:

I have added the Header file "using Vishal.TextFileUtils"

Vishal.TextFileUtils is the Supporting header file. You can see it( "http://vishalseth.com/blog/2007/02/20/vishaltextfileutils-library-for-working-with-delimited-text-file-formats).

namespace ConsoleApplication12
{
class Program
{
static void Main(string[] args)

{

DelimitedFile df = new DelimitedFile(new FileFormat(PredefinedFormats.CSV), @"C:\GCProject\Input Example.csv");

foreach (LineEntry le in df)
{
Console.WriteLine(le.FieldValues["MyColumnName"]);

for (int i = 0; bool.Parse(df.Count.ToString()); i++)
{
le.FieldValues["MyColumnName"] = "MyColumnData";
}
}
df.Save(@"C:\output.xls");

}
}
}

When Run the application, I found the error like KeyNotFoundError(I have bold where I am getting the error). Which I not able to find what is happening.

So, the general flow for this application is:

1. CSV Input File is created by user or external application
2. My Application reads data in from CSV file
3. My Application converts records from the CSV file to a new format (xls format)
4. My Application outputs to text file.

Please let me know if you require additional information.

Thanks & Regards,
Liyakhat.

Erm... I can do that without writing 1 line of code. Excel will happily open a CSV text file.

Or is this Homework and you just can't be bothered?

That's your problem, there is no field called "MyColumnName" in FieldValues. Make sure that you type in the correct string here.

Hi,

in your form:

- set KeyPreview true
- install a KeyPress handler, have it check for letter 'f', if so check
CTRL key is down (use Control.ModifierKeys), if so create a new dialog form and
show it with ShowDialog; you may choose an OpenFileDialog or something you
design yourself.

That should do it.
