Server.MapPath is only for a web environment. For a windows forms app you would need to know the whole path.

Hi,
Does anyone know how to format a floppy disc without using DOS or Windows format windows. I am looking for code to format a floppy.

This is driving me mad. I have been working on windows forms application for a while and suddenly straight out of the blue the visual style for the buttons stopped working. That is, they go back to looking like buttons in Windows 2000. All other controls that support visual styles seem to be working ok.
Does anyone know anything about how to fix this? The really wired thing is that when I tried to do a new form in the same project all works ok for a few compilations and then the buttons just go back to ugly mode again.
By the way I’m using .Net 1.1 and visual studio 2003.
Regards Johan

I just found the solution to the problem, here it is:
Just after calling Application.EnableVisualStyles() call Application.DoEvents()

Hi,
I have a form where some selectioncriteria can be set. The form contains some comboboxes and also some datetimepicker's.
I want the following: when the form is loaded, I don't want any date to be shown in the datetimepicker's. Only when the user clicks the control, a date can be selected.
I tried:
dteFixDate.Value = Nothing , but this is not allowed.
dteFixDate.Text = "" , when the form is loaded, the current date shows in the control.
In fact, I want to use the values of the datetimepicker's in my SQL. So when no date is set (blank datetimepicker text), the date is not to be taken into account.
Does anyone know a way to do this. Or am I totally wrong in what I'm doing and is there an easier, cleaner way to obtain the result?
Thanks in advance, 
|

I don't think you can set a DateTimePicker value to null/nothing/etc.
DateTimePickers have a .ShowCheckBox property which puts a checkbox next to the date. With the .Checked property set to false, the control is effectively disabled (but it still shows a date). As soon as the user selects a date, .Checked = True.
All you need to do is .ShowCheckBox = True and .Checked = False when you load the form. When you want to get the date just see if .Checked = True, indicating that the user has entered a date.
Hope that helps!

Hi all
i have successfully managed to use dot net objects in perl, but i can't find out how to initialize a dot net object that takes an array as a parameter.
so basically the scenario would be:
--- PERL CODE ---
my($component) = Win32::OLE->new("componentTest.componentTestClass");
if (defined $component)
{
print "Created component object\n";
$component->initialize(@array);
# or even better a referenced array: \@array
my($result) = $component->main();
print "\nRESULT = " . $result;
}
else
{
print "COMPONENT NOT FOUND\n";
}
any ideas anyone?

Hi im using vb.net application to print data through dot matrix printer. what i need to do is once a printout is taken the paper should roll back to its starting position.
Is there any way in .net to handle such functionality of printer.

That is a function that should be built into the printer itself. Try looking up Tear Off in the manual to see how it works.
On my old LQ-850, I didn't have to do anything in code to use it, nor did I have to hit any buttons on the printer.

Problem
I am developing a system that uses Crystal Reports. I have Crystal report v8.5 on my PC and when I display a crystal report via VB.Net (2003), the report is displayed. The problem is that when I do the same report on a user's PC the report is not getting displayed. There are no error messages. What am I doing wrong.
Here is a sample of my code that is on the click event of the form....
'Load Crystal Report's rpt file
Dim cr As New CrystalDecisions.CrystalReports.Engine.ReportDocument
cr.Load(strReportPath)
param1Field.ParameterFieldName = "PassParam"
param1Range.Value = sPassParam
param1Field.CurrentValues.Add(param1Range)
param1Fields.Add(param1Field)
CrystalReportViewer1.ParameterFieldInfo = param1Fields
Dim rpt As New CrystalDecisions.CrystalReports.Engine.ReportDocument
CrystalReportViewer1.ReportSource = strReportPath
CrystalReportViewer1.Refresh()
'Set the CrystalReportViewer's apperance and set the ReportSource
CrystalReportViewer1.ShowRefreshButton = False
CrystalReportViewer1.ShowCloseButton = False
CrystalReportViewer1.ShowGroupTreeButton = False
CrystalReportViewer1.Zoom(55)
'CrystalReportViewer1.ReportSource = cr
Any ideas?
