Does a textbox control, placed on a form, have a inhereted methid in vb.net to do a alphanumeric validation? If not, what is the easiest way to achieve this? Thanks.
|
|
|
|
|
u can fetch the value of textbox and store in a string variable and perform the validation on the string variable.
|
|
|
|

No, you have to code it yourself.
You can make your own TextBox by creating a class, inheriting from TextBox, and adding validation code by handling the KeyDown event and screening out characters that are not numbers.
You can find lots of example by just simplying searching[^] the articles here on CP.

Have you seen the DetectUrls[^] property of the RichTextBox control? All you have to do is set this property to True, then handle the LinkClicked event.

So handle the LinkClicked event, get the URL from the event arguments and set the label text with it.

This is normally done with some kind of Insert menu, not typing. The user leaves the I-beam where the isnerted item will go, then clicks on a menu and picks what should be inserted at that point.
You've complicated your app by trying to do it with typing a marker. Considering your short timeframe, I would suggest dropping this and doing it with the much simpler menu-driven solution.
Part of turning in a project on time is knowning what features are critical to your application and which are "nice to haves". If your "nice to have" features will make your project late, they're not worth putting in. Keep in mind, you're being graded on what you turn in as a finished project.

This is a bit more complicated. You'd have to create a form that allows you to enter some text and click an Insert button. You'd show this form with a ShowDialog call. When the Insert button is click on that form, it should set its DialogResult property with some value that you define, and it should set a public field that contains the text to be inserted.
When the ShowDialog call returns, you'd check the DialogResult return value and act appropriately, using the text in the public field to insert the text.
Form2 should not know ANYTHING about Form1 at all. It's functionality should not care that Form1 even exists and should not depend on the existance of a RichTextBox. This dialog should be concerned with handling a little user input and setting its DialogResult based on which button on that form with clicked.

The only way to do this reliably is to write global keyboard and mouse hooks. There's a few articles here[^] on CP. The code is in C#, but is easily converted to VB.NET.

check my code syntax error in "For Fentry To Lentry" "sql" "cmd"
What does this code do! Want to automaticaly generate number in my database(SQL).Just entering first no. in TextStart.Text and last no. in TextEnd.text.
Example:
first no.: 1
Last no.: 10
it will record the no.1,2,3...10 in the database.
myAdapter.SelectCommand = New SqlCommand("Select * from tblReceipt", MainConnect)
myBuilder = New SqlCommandBuilder(myAdapter)
Try
myAdapter.Fill(tblOR)
Catch ex As Exception
MessageBox.Show("Cannot find the information needed." & newLine & "Check Database or contact programmer!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try
Fentry = Convert.ToInt32(TextStart.Text.ToString())
Lentry = Convert.ToInt32(TextEnd.Text.ToString())
MainConnect.Open()
For Fentry To Lentry
sql = "INSERT INTO myTable(Number) VALUES (" + Fentry + ") "
cmd = New SqlCommand(sql, MainConnect)
cmd.ExecuteNonQuery()
Next

The syntax of the For command is:
For counter_variable = start_value to end_value
---
b { font-weight: normal; }

Hello,
The following dataset returns the results of this table:
Dealer Item Description Lang
12345 4567 numbers E
In my code, how would I retrieve the value in the Lang column? I need to be able to retrieve that value in my IF statement so that I can use a specific form for that dataset as such:
Me.TableAdapter1.Fill(Me.DataSet.tblitems)
If Me.dataset.tblitems (Lang coloumn = E) then
Me.ReportViewer1.RefreshReport()
else
Me.ReportViewer2.RefreshReport
End IF
Thank you,
|
|
|
|
|
If dataset.tables(y).rows(x)(z).tostring="E" Then
end if
y-The number of the table
x-The number of the row
z-The number of the column

Hi,
I am facing a strange problem in this.
http://www.codeproject.com/vb/net/vbmp3header.asp
When i try to trap the value of artist and title as:
dim artist as string
artist = objMP3V1.Frame(MP3ID3v1.FrameTypes.Artist)
dim title as string
title = objMP3V1.Frame(MP3ID3v1.FrameTypes.title)
dim new Name as string
newName = artist + title
The variable 'newName' does not contain the values of both title and artist. It only contains of artist whereas individually i am able to see the values of artist (msgbox(artist)) and title (msgbox(title)).
Pls reply within half hour.......

You're joking right? This is an all-volunteer effort forum. Not a tech support line. If you want immediate help, call Microsoft. Don't forget your credit card.
But, as to your problem, string concatenation is done using:
newName = artist & " - " & title

I tried this also, then also it is not concatenating.
Both ways i do not get a compilation error, but only one value is stored in 'newName'
|
|
|
|
|
dim artist as string
artist = objMP3V1.Frame(MP3ID3v1.FrameTypes.Artist)
dim title as string
title = objMP3V1.Frame(MP3ID3v1.FrameTypes.Title)
dim newName as string
newName = artist + title
If this is indeed the code your using, then the only possibility is that the call to objMP3V1.Frame(MP3ID3v1.FrameTypes.Title) returned an empty string.
Try copying and psting your code next time, not just typing what you think you used. We've all tried to chase down bugs in code that wasn't actually being used around here and it wastes a lot of time.

yes.... u r right. 1) i will copy the code rather than typing it here.
2) objMP3V1.Frame(MP3ID3v1.FrameTypes.Title) .This code return the value of title and similarly objMP3V1.Frame(MP3ID3v1.FrameTypes.Artist) returns the value of Artist. But when i try to concat by either i) artist + title or ii) artist & title ---- it returns only artist's value.
But this problem was solved when i created 3 label fields :-
label1, label2, label3. what i did was:-
label1.text=objMP3V1.Frame(MP3ID3v1.FrameTypes.Title)
label2.text=objMP3V1.Frame(MP3ID3v1.FrameTypes.Title)
label3.text=label1.text + "-" + label2.text
With this code it was concatening. But in this case also if i make these 3 label fields invisible ('label1.visible=false') then it doesn't concatenate again. So i have to always set the visible property to true of these 3 labels. This is quite strange though.
Anyways thanks a lot for your help.
Regards
