Normally, no. But that and what's causing it to crash depends on what your app is doing and with what resources.

In my opinion, it is not relatet to the file system (FAT or NTFS). I used to use windows 98 and found it is very difficult when it have a problem. Its always display kernel error when there is lack of the memory resource. While windows 2000 and windows xp, change the style to manage error handling in windows environment. It seem that most of application could run very stable whether its have some error occure.

Win 98 has a very limited amount of GDI resources, which can cause this sort of problem.
1) On XP, open the task manager
2) Choose View/Select Columns...
3) Check the GDI Objects checkbox
4) Monitor this value in the listview as you use the application.
If it continues to rise, without ever dropping, then you probably have some sort of resource leak in your app. If it is just very high, the app will probably crash on Win 98.

Thank you for you help. The GDI object on my app went up to 128 max, and now has settled as 126. Well now all can do is take this information to my boss as see what he has to say about upgrading.

The filesystem is irrelevant. do you write this program in visual basic .net or with common visual basic ? if your write with .net then check whether .net framework is still installed. if your wirte in common visual basic check your ocx or activeX files or check they are correctly registered.

Being written in visual basic .net the framework is fine because I have the same problem on two different computers running 98. But the one computer running 2000 can handle the program just fine.
If I break up the GUI in to more then one form it does work in 98 just looks like crap.
Thanks for the help

summers over school is in, yet again.
heh, well, for the past 5 months or so on my school vacation, i hadnt used VB.net. now im lost again :S
first off: im not asking you to do my homework, im asking for help..
my project is as follows: two text boxes, and one button. i need to write a program to find the difference (number of days) between 2 entered days (ex, day1 = monday, day2= friday, difference = 4 days.
i have an enum like this:
Private Enum DaysOfWeek
Monday = 1
Tuesday
Wednesday
Thursday
Friday
Saturday
Sunday
End Enum
i also have 2 variables that i made of the enum type (startDay and endDay). i set startDay and endDay's value = their respective textboxes.text, which the user enters a day of week. i get cast from string to integer error (i know, because enums must only be integer values, right?)
so how can i do this? (sorry if being broad, again, im not asking you to do my homework for me, im asking for help.)
thank you

Instead of casting string to enum use the Enum.Parse method to convert the string to Enum.

im off to bed, but, i WILL definetly check it out. iv never heard of that method before, ill look into it!
thank you very much!

Hello everybody. I am new to VB.NET and i have the following code:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim objPrint As New System.Drawing.Printing.PrinterSettings
Dim strItem As String
Dim strPrinters As String
For Each strItem In objPrint.InstalledPrinters
cmbPrinter.Items.Add(strPrinters & strItem)
Next
End Sub
I am able to get all the list of available printers and i want when i click on one of them a list to be filled with all available paper sizes for that printer. So far no luck. Can anyone help me. Thank you in advance...

Thank you Anonymous. It has all the information needed. But still I can't seem to be able to make the paper size combobox to get the papers sizes of the printer that i have clicked on the printer combobox. I can only seem to be able to get the default's one. ARGGG!!! What am i doing wrong?
HEEEEELPPPPP

Without seeing your code, it's impossible to tell you. PaperSizes returns a collection. Are you enumerating the collection it returns or just using the first item from it?
We need to see the code...

Ok here is the code so far:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim objPrint As New System.Drawing.Printing.PrinterSettings
Dim strItem As String
Dim strPrinters As String
For Each strItem In objPrint.InstalledPrinters
cmbPrinter.Items.Add(strPrinters & strItem)
Next
End Sub
Private Sub cmbPrinter_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmbPrinter.SelectedIndexChanged
' Add list of supported paper sizes found on the printer.
Dim searchstring As String
Dim SearchChar As String
Dim MyPos As Integer
Dim i As Integer
Dim pkSize As System.Drawing.Printing.PaperSize = Nothing
SearchChar = "A4"
For Each pkSize In printDoc.PrinterSettings.PaperSizes
lstPaper.Items.Add(pkSize.PaperName)
Next
For i = 0 To lstPaper.Items.Count - 1
lstPaper.SelectedIndex = i
searchstring = lstPaper.SelectedItem()
MyPos = InStr(searchstring, SearchChar)
If MyPos = 0 Then
lstPaper.Items.Remove(0)
Else
paperToUse = searchstring
End If
Next
updateDisplay()
End Sub
I can fill the combobox of the printers and the list box of the papers. BUT when i click on another printer the program DOSEN'T give me the list of the paper sizes on the new selected printer. It's like it stucks in the paper sizes of the default printer...
HEEEEEEEEEEEEEEEEEEEEEEEEEELP!!!

I was able to load the datagrid correctly and fill it. What I am trying now to accomplish is how to highlight a whole row when I user either tabs down or clicks the row. As of now it highlights just one column of the row. I want to be able to highlight the whole row and have a user click the row to get the info the user is requesting.
Thanks

That is the right track but if a user clicks on (row 1 column 3) then all the data for (row 1 column 1) and (row 1 column 2) disappears and the whole row is highlighted. I have seen this done in programs so I know its possible.
Right now my rows alternate colors with light blue and baby blue. When a user selects a row they want to view, then I want to highlight that row to stand out like with a yellow or even a darker blue to make it look different from the rest.
Thanks

you've probably sorted it now but a really simple way would be
Private Sub DataGrid1_CurrentCellChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGrid1.CurrentCellChanged
Dim oCell As DataGridCell
oCell = DataGrid1.CurrentCell
Dim lRowNum As Long
lRowNum = oCell.RowNumber
With DataGrid1
.Select(lRowNum)
End With
End Sub

You could make your own input box.
Make 2 forms in a blank project
Drag a CommandButton onto Form1
and a TextBox onto form2
'FORM1 CODE
Public Function InputBox2() As String
Form2.Show vbModal
InputBox2 = Form2.Variable
End Function
Private Sub Command1_Click()
Command1.Caption = InputBox2()
End Sub
'FORM1 CODE
'FORM2 CODE
Public Variable As String
Private Sub Text1_KeyPress(KeyAscii As Integer)
If KeyAscii = 13 Then
Variable = Text1.Text
Unload Me
End If
End Sub
'FORM2 CODE
Pretty simple, from there u can add whatever u want
