Just take a look through the beginner articles here. The best way to learn would be to think of a simple application you want to write, start writing it using Google etc to help you. If you become really stuck then post a question here.
I find you always learn more by hands-on-experience
As of how to accomplish this, have you ever tried Google?

Hi,
I have a datagrid that is binded to a datatable (in form of a dataview). I have a requirement that when a particular column in the grid has a value (say 'stat'), then the entire row should be painted in red(the text should be red) else black.
I have extended DatagridColumnStyles for my custom columns. In the paint method, i check for the value in the dataview and accordingly set the forebrush.However, when the user sorts the grid, although it shows the dataview to be sorted, still, the value retrieved is incorrect. I use the row parameter of paint to get the value from the dataview.
Here is the sample code
protected override void Paint(Graphics g, Rectangle rect, CurrencyManager cm, int row, Brush backBrush, Brush foreBrush, bool rightAlign)
{
bool isStatRow = false;
DataRowView rView = null;
try
{
DataView dview = DataGridTableStyle.DataGrid.DataSource as DataView;
if( dview != null )
{
string strStat = dview.Table.Rows[row]["ORD_SCHEDULE_INTERVAL"] as string;
if( strStat != null )
{
string val = strStat.Trim().ToLower();
if( val.IndexOf("stat") == -1 )
isStatRow = false;
else
isStatRow=true;
}
}
}
catch(Exception ex)
{
}
g.FillRectangle(backBrush, rect);
string str = HelperClass.GetString(GetColumnValueAtRow(cm, row), NullText);
if( isStatRow )
{
g.DrawString(str, DataGridTableStyle.DataGrid.Font, new SolidBrush(Color.Red), rect);
}
else
{
g.DrawString(str, DataGridTableStyle.DataGrid.Font, foreBrush, rect);
}
}
The code works when the grid is first painted, but once the same is sorted, this returns me errorneous values and thus paints the color wrongly. I tried using currencymanager.Current also but to no use.
Any ideas???
Please respond

Hello,
I have the SID of a user and the SID of a group. Now I need to check if the user is member of that group... So I think I should get the members and there SID of a group and then check with a for-loop if the SID is present. Is there anyone that knows how I could do that?

Yes! Use SelectedIndices instead.

Same as you would in PC:
MyListView.Columns.Add("MyNewColumn");
NB.
There is an icon in MSDN at the left of each member of a class in the "all members" page, indecating that it's available in .Net compact framework or not. It resembles a PDA. Use those only.

Hi, Thanks for your reply.
I tried that one.
ListViewItem item = listView1.SelectedIndices[0];
But error coming:
Cannot implicitly convert type 'string' to 'System.Windows.Forms.ListViewItem'
please help me...

Hello
Sure you can't do that. SelectedIndices is a collection of integers. You use them this way:
ListViewItem MyItem;
foreach(int X in MylistView.SelectedIndices)
{
MyItem = MyListView.Items[X];
}
Or more simply if you want to access a certain item -provided that you are sure that there are atleast one selected item-:
ListViewItem MyItem = MyListView.Items[MyListView.SelectedIndices[0]];
If there are no selected items, or you put a number larger than the number of selected items you will get an out of bound error. OTOH I guess you already know that!!

Hi Thanks a lot.
Now ok.
But still i want to append the text in listview.
listView3.SelectedIndices = new Font("Arial", 10, FontStyle.Bold);
listView3.Items.Add(name + " : " +message);
listBox1.Items.Add("\n");
That one tried, but still notSupportedException coming..
please give your advise
Thanks&Regards

Hello
What I understand from your post is that you want to append some text at the end of each selected item in the listView.
First, let's we go through your code:
Sri harini wrote: listView3.SelectedIndices = new Font("Arial", 10, FontStyle.Bold);
Here you are assigning a font object to a collection of integers!! Not appropriate.
Sri harini wrote: listView3.Items.Add(name + " : " +message);
Assuming that message is a string, you are trying to add a string to a collection of ListViewItems! Again same problem
The last line is same as the second. So, your problem lies in not matching your types. You must know which type to use. Usually I keep my MSDN as long as I'm programming. It helps a lot
Now to do the same thing, I suggest this code:
foreach(int Index in listView3.SelectedIndices)
listView3.Items[Index].Text += ": " + message;
You can't change the font of items because it's not supported in compact framework -BTW: I revised MSDN for that;P-
I don't understand why would you add a newline to the end of your item's text?? But if you insist just uncomment the code I commented -after removing the semicolon of course-

I don't think I got you right!! Are you trying to add a cs file to your project as a new Add-in project??
The way I know it is:
Solution Explorer => Right Click on Project's name => Add => Existing item

Hi!
Need your ideas urgently! I have a metafile which I wish to convert to PDF on the fly. The idea is to create a metafile template with placeholder text, which will be parsed and replaced by user information at runtime before generating the PDF. When editing the metafile, I have progressed to the following steps:
1. Called the Graphics.EnumerateMetaFile() method, which calls the callback method (lets call it ‘Play’)
2. Called the callback method and obtain the record data
public bool Play(EmfPlusRecordType recordType, int flags, int datasize, IntPtr data, PlayRecordCallback callback)
{
byte[] dataArray = null;
if (data != IntPtr.Zero)
{
dataArray = new byte[datasize];
Marshal.Copy(data, dataArray, 0, datasize);
}
3. Checked whether the record pertains to writing text on the wmf as follows:
if (recordType == EmfPlusRecordType.DrawString)
4. Called the Metafile.PlayRecord() method to draw the new metafile.
mf.PlayRecord(recordType, flags, datasize, dataArray);
What I’m unable to do is, to parse the dataarray (which contains record data), such that I can replace existing text with new text.
Thanks a LOT for any insights.
Regards,
Kunaal

Could you elaborate on that?
I understand that you want to set the size of something, but I have no idea if you are talking about window size, font size, or whatever.

Hello
First of all welcome to CP.
Second, two things -among other things- are considered very rude here
1- Reposting your same question in the same forum within a short period even if you didn't get an answer on your previous post.
2- Cross posting questions in inappropriate forums.
So, please delete your previous message, and keep this one.
Now, to your issue. Please post the code that's troubling you, or in your case, more details about the size problem.
Regards

The maskedTextBox control has the mask property, which set the default format of the text of this control. when the user haven't inputed any text in it, the text property of the control isn't "", the text of it is determined by the mask property of maskedTextBox control, and in my programm the mask property of the control is dynamic and changed by the condition. I need to judge if the user haven't input anything in this control. How can I do it?

Hello
Try comparing the Text property with the Mask property
Regards
|
|
|
|
|
But when the mask property is "0000/00/00",the default text of this control is " / / /",they are not equal.
|

Hello
Two more approaches:
1- Check first character of text by IsChar() and IsDigit() methods to see if the user acually did make any input. You can also check the entire string using a forech loop.
2- Handle the TextChanged event, and store the updates in a bool called modified. Set it to true when the user makes input, and top false when the user deletes all characters.
Regards

Take a look at the IncludeLiterals property which will remove all formatting from the Text property, i.e. you will get the raw values entered by the user without any formatting provided by the mask property.
As of how to accomplish this, have you ever tried Google?

Hello
Looks like I've been a stray a bit with this one!!
The code should be like this, I think
maskedTextBox1.TextMaskFormat = MaskFormat.ExcludePromptAndLiterals;
MessageBox.Show(maskedTextBox1.Text);
