Hello,
I have checked the working of the code and everything seems to be working.
I get a file created with text in it and also get the strings written in OutPut Window.
However, I am not sure what exactly you are looking for. If I am assuming correctly, are you
looking to write the text on the form or what. Can you explain the things in detail?
Regards,
Allen

Add a label to your form. Then do this
label.Text = File.ReadAllText(path)

I can see nothing wrong with your code but then again I am a C# developer not a VBer (anymore). However the one thing I will point out is to dispose of your streams. In C# there's a nice using statement but in VB I presume you'll have to do something like the following:
Dim sr As StreamReader = File.OpenText(path)
Do While sr.Peek() <> -1
Console.WriteLine(sr.ReadLine())
Loop
sr.Close()
sr.Dispose()
I doubt it. If it isn't intuitive then we need to fix it. - Chris Maunder

hi
is their is away to check the first three letter from string
|
|
|
|
|
Hello,
You can use the Substring() method to implement the same.
For example:
<br />
<br />
Dim str As String = "Test String"<br />
MsgBox("First Three letters: " & str.Substring(0, 3))<br />
<br />
I hope this will help.

Load the XML into the XmlDocument class. This impliments the standard W3C DOM for accessing XML. Then you can do something like
doc.SelectNodes("/Gateway/URL")
to get a collection of the URL nodes, which you can then iterate over and examine. The language used to selecte nodes is called XPath.

Communication between multiple instances of a program with Shared members and events.
This works fine as long the instances are started by the same thread.
If I start multiple instances by clicking the exe file it doesn’t work.
What to do?

You need to create cross process communication, probably using WCF.

Thanks mr Graus,
I have to stay with .NET 2.0 and for WCF it seems that 3.0 is needed
What other options are there?

Hi all,
i want to convert RTF to PDF programmatically.
i had tried itextsharp also , but i am not able to figure out what to do
is there any one experience in this area
thanks in advance
|
|

If you're planning on writing your own component then you'd probably need to look at the RTF Specification, figure out how to read it and then map these different things onto the iTextSharp interface. It's a fairly obtuse interface I know (I've worked with it) but the biggest issue I see here is parsing the RTF.
I doubt it. If it isn't intuitive then we need to fix it. - Chris Maunder

hi,
i m assuming you are asking about datagridview. In vb.net 2005 following statement works
Dim Str As String = "YourValue"<br />
DataGridView1.Rows(DataGridView1.Rows.Count - 2).HeaderCell.Value = Str
hope this also works in vb.net 2003

I guess sometimes it's being shown as a different datatype, one to which is can be converted ?

It's probably the formatting property in your crystal report. Since the variable is Boolean, the formatting in the report will determine "Yes" or "Y".

All I want to do is create a VBA script in Excel 2003 where I search through a spreadsheet, and delete every row where column E in the row (a date and time field) does not contain the text 2008.
So e.g.
If E1 contains 2008 delete row 1
If E2 does not contain 2008 keep this row (row 2)
If E3 contains 2008 delete row 3
Continue until no more values
How would I do this please?
I have tried to do it using in built features on Excel but i can only find and replace...etc and the macro recording isnt really helping much hense why i am asking for your help.
Thanks

The Rows collection of the worksheet has a Delete function which you can use to delete an entire row.
For example: ActiveSheet.Rows(1).Delete will delete row 1.

Hi
I want to know ..How to validate an event handler whether it is triggered at the
time of form load or not ..
Please help me with any example code.
Thanks

You can't validate it, because it never fails to fire. You can handle it and check there, if you want, but if it,s for example, the form load event, it will fire.

i have managed to create a program which connects to a cam and also copies a frame to another picture box. the problem now is how to compare the two picturebox QUICKLY...... in my code i had included a formula that was used in vb6. but now cannot be used cause of the picturebox.poin(x,y) was removed in vb.net which makes it harder to convert...
this was in vb 6.0
Private Function Different(ByVal a As Long, ByVal b As Long) As Boolean<br />
'Checks different of two colors<br />
ar = a Mod 256: a = a \ 256<br />
ag = a Mod 256: a = a \ 256<br />
ab = a Mod 256: a = a \ 256<br />
<br />
br = b Mod 256: b = b \ 256<br />
bg = b Mod 256: b = b \ 256<br />
bb = b Mod 256: b = b \ 256<br />
sense = 255 - Text1.Text * 5<br />
<br />
Different = (Sqr((ar - br) * (ar - br) + (ag - bg) * (ag - bg) + (ab - bb) * (ab - bb)) > sense) 'formula for counting different<br />
End Function<br />
<br />
Private Sub Timer1_Timer()<br />
'getting picture from camera<br />
SendMessage mCapHwnd, GET_FRAME, 0, 0<br />
SendMessage mCapHwnd, COPY, 0, 0<br />
Picture1.Picture = Clipboard.GetData: Clipboard.Clear<br />
<br />
<br />
stepp = 3 'Grid dense<br />
<br />
Dim qan, qann As Long<br />
qan = 0<br />
qann = 0<br />
<br />
For i = 1 To Picture1.Width / Screen.TwipsPerPixelX Step stepp<br />
For j = 1 To Picture1.Height / Screen.TwipsPerPixelY Step stepp<br />
<br />
If Different(Picture1.Point(i * stepp * Screen.TwipsPerPixelX, j * stepp * Screen.TwipsPerPixelY), Picture2.Point(Screen.TwipsPerPixelX * i * stepp, j * stepp * Screen.TwipsPerPixelY)) Then<br />
Picture1.Circle (i * stepp * Screen.TwipsPerPixelX, Screen.TwipsPerPixelY * j * stepp), 1, RGB(255, 0, 0)<br />
qann = qann + 1<br />
End If<br />
<br />
Next<br />
Next<br />
Label1.Caption = Int(qann * 100 / 910) & "%" 'Counting motion in percents<br />
ProgressBar1.Value = Int(qann * 100 / 910)<br />
End Sub<br />
