View 6 Replieshow to create an error message by message box to tell the user to enter a number only if they key in a character value?
I MEAN AFTER THEY PRESS THE CALCULATE BUTTON
Private Sub btnCalcFat_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalcFat.Click
Dim intFat As Integer
intFat = Integer.Parse(txtFat.Text)
lblResultDisplay.Text = txtFat.Text * 9
End Sub
My text box is call txtFat
I have couple of questions with datagridview 1.How to handle the Enter-Key when the user edited the columns value.?I mean, without changing the columns values we can suppress the enter-key by following. No problem. It's working Fine.
Private Sub DataGridView1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown
If e.KeyCode = Keys.Enter Then
Dim numCols As Integer = DataGridView1.ColumnCount
Dim numRows As Integer = DataGridView1.RowCount
[code]....
But after if I select any one column & changed the values then if I press <Enter> it's moving to next row. But I want to move it to next column..
2. With Datagridview - I have a column for date. and it's defaut format is mm/dd/yyyy. But Iam looking to read the date by "dd/mm/yyyy" format. Also if the user feed wrong date format then it has to display my Error message. "INVALID DATE"
I have 5 textboxes embedded in a datagrid that require a date format (mm/dd/yy), but can be left empty if user doesn't have date. User can poplutes these textboxes for multiple records and hit submit button. On the submit i loop through the grid. If dates are populated AND they are in the correct format then I call a stored procedure that inserts the record into a table. If any of the dates that are populated in the textbox is not a date or in the incorrect format I need to display error message in a label. I got all this to work, but if it throws error message all the data in the grid is wiped out.
How can i keep data in each textbox and still display the error message?

I am trying to display a message box in VB.NET. This should be simple but I cannot get it to work. I have coded in VB before and used MsgBox("Message") but in VB.NET i understand its MessageBox.Show("Message") but i cannot get it to work. Its saying MessageBox is not declared but what do you declare a message box as?
View 1 RepliesI have a simple message box and it's not displaying when i run my subroutine. I debugged to verify that it's going into the code and it does; however, the message box just doesn't display and I don't know why.
here's the part of the subroutine that the message box is in:
<code>
If bSuccess = True Then

create a message box that stores my user name, message, and post datetime into the database as messages are sent. Soon came to realise, what if the user changed his name? So I decided to use the user id (icn) to identify the message poster instead. However, my chunk of codes keep giving me the same error. Says that there are no rows in the dataset.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim name As String
Dim icn As String
Dim message As String

I am querying a db based on some conditions and then I am putting these data in a text file. This is done by a for Loop. Is it possible to have some message box telling that data1 is being copied, data2 is being copied, etc. Some kind of dynamic textbox, telling what is being done at the background.
View 6 RepliesI always useMe.Cursor = Cursors.WaitCursorfor a time taking functions like hitting the DB.Now if any exception occurs, I'll display the error message as:Msgbox(ex.Message)So before displaying any message, I need to reset the cursor to default.Is there a simple way to do it at in one place instead of writing it in all catch blocks.
Is there a way to inherit MessageBox class and override the functions?Other wise I need to code it in all the catch blocks or handle all the exceptions at one place which I don't want to modify the whole application now.
this is a web response:
<RESP>104</RESP><BAL>0.72</BAL><VER>4</VER><UID>171683</UID><PID>152045</PID><MSG>Invalid password</MSG>
how to get this done im try to do is to get the <resp>104</resp> if this is the response my message box in vb says invalid username or password?
I'm having a little difficulty sending mail using VB.Net (2003). I'm attempting to use the company mailhost, and the usual System.Mail methods to do the send, but i get blocked by the "Could not create CDO.Message" error. I've been on MSDN, and looked through the various threads on here, and they all point to a problem with the dll.
The trouble is, that this is not a consistent error. Sometimes it works, sometimes it doesn't. It will work on one user's PC profile, but not another's on the same PC. It will send a mail for a particular user, and then 2 mins later fail to send the same mail. I've tried re-registering the dll anyway, and faffing about in the registry as per the MSDN recommendation, but no joy. And because it's so inconsistent it's proving pretty tricky to narrow down the cause.

View 6 RepliesI have an excel file with few macros written in VB language..
Now I want to create an installation file that will install this Excel file onto clients machine at a predefined (or user chosen) location just how a normal installation file works.. I also want the user to put a serial code that will be validated (don't know how)..
I think making an installation file in VB.NET is possible. My question is can I make installation file with just an excel in it and the feature of validating serial code using VB.NET?.. If it is possible that would be great.. otherwise what other solutions do I have..
I posted this on the Deployment forum, but you guys reply so much faster

I created a Visual Studio 2005 application that works and installs on other user's computers, but not the way I want.
1. I want to create a single file that I can distribute to any user so when he clicks it, the application will be INSTALLED.
2. When it installs, it chooses to do in its own location. It does not give the user an option to save or install in a specific folder (where the application will be used because other files are there). How do i allow the user to save the the application in a specific folder?
3. I would like a single file that the user clicks to RUN the application. Is that the in*.exe?
