Create a variable that stores the selection in the listview at the moment it gets made or changed. As an added bonus it is also easier to clean up if you have to, for example due to another choice made elsewhere on your form.

Hi guys an gals,
I have a form using databinding to a dataset. Whenever the user navigates to another record I check if datasource.HasChanges is true, and if so I ask whether the user wants to save changes. All this works perfect on my pc, but on the users' pcs it basically asks to save on EVERY navigate and even form load, even though there were NO changes made.
Here is the code snippet:
Private Sub OrganisationBindingSource_CurrentChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles OrganisationBindingSource.CurrentChanged<br />
Try<br />
If Me.OrganisationBindingSource.DataSource.HasChanges = True Then<br />
If (MessageBox.Show("Record has changed. Save changes?", "Save", MessageBoxButtons.YesNo, MessageBoxIcon.Exclamation) = Windows.Forms.DialogResult.Yes) Then<br />
Me.OrganisationBindingSource.EndEdit()<br />
Me.SoftwareBindingSource.EndEdit()<br />
Me.ContactBindingSource.EndEdit()<br />
Me.QuoteBindingSource.EndEdit()<br />
Me.OrganisationTableAdapter.Update(Me.CRMDataSet.Organisation)<br />
Me.SoftwareTableAdapter.Update(Me.CRMDataSet.Software)<br />
Me.ContactTableAdapter.Update(Me.CRMDataSet.Contact)<br />
Me.QuoteTableAdapter.Update(Me.CRMDataSet.Quote)<br />
Else<br />
Try<br />
Me.OrganisationBindingSource.CancelEdit()<br />
Me.SoftwareBindingSource.CancelEdit()<br />
Me.ContactBindingSource.CancelEdit()<br />
Me.QuoteBindingSource.CancelEdit()<br />
Me.OrganisationBindingSource.DataSource.RejectChanges()<br />
Catch<br />
End Try<br />
End If<br />
End If<br />
Catch err As Exception<br />
MessageBox.Show(err.ToString.Replace("'", ""))<br />
DH.RunQuery("INSERT INTO Log_Error (Message, Process) VALUES ('" & err.ToString.Replace("'", "") & "', '" & Me.Name & "')")<br />
End Try<br />
End Sub
Any ideas on what could cause this? As I say, this does not happen on my pc, so I dont know how to debug it??? 
Thanks in advance
Ed

Hi Ed,
This code snippet shows the code that gets executed when the user navigates. You say that this code gets executed at the wrong time (also). So it seems to me that you're looking in the wrong place. If you debug this it will always run correctly, and apparently also on the other pc. You will have to look at the code that precedes the navigation event. Somewhere a piece of code is triggering the event or allowing some user action or background process, which your pc does not allow, either by configuration or because of some program that is running on either pc.
Good luck,
Johan

Hi to all
Please tell me how i will handle this code in vb.net
the code is there in vb and i am converting that into .net
<br />
Dim oFSO As New FileSystemObject<br />
If oFSO.FolderExists("C:\recordedFiles") = False Then oFSO.CreateFolder ("C:\recordedFiles")<br />
If oFSO.FolderExists("C:\recordedFiles\TataAig") = False Then oFSO.CreateFolder ("C:\recordedFiles\TataAig")<br />
<br />
Filename = agent_login_Name & ApplicationNumber & "_" & Format(Now, "YYYYMMDD_HHmmss") & ".Wav"<br />
filePath = "c:\RecordedFiles\TataAig\" & Filename<br />
<br />
Shell App.Path & "\Harddisk.exe -preset " & Chr(34) & App.Path & "\LameCfg.hdp" & Chr(34) & " -record -output " & Chr(34) & filePath & Chr(34) & " -minimize"<br />
<br />
g_FL_Recording_Started = True<br />
lblRecordingStatus = "ON"<br />
cmd_Start.Enabled = False<br />
cmd_stop.Enabled = True<br />
Call log_error("Start Recording ")<br />
|

|

Look at the System.IO.File and System.IO.Directory namespaces where you will find things like
System.IO.Directory.Exists(myFolder)
and
System.IO.Directory.Create(myFolder)

I'm not 100% on this, but I'm pretty sure you can do this through WMI.

Try setting your Property DataType as an Enum. For example :-
Enum DataTypes<br />
Date=1<br />
Text=2<br />
Number=3<br />
End Enum<br />
<br />
Property DataType As DataTypes<br />
Get<br />
'Your code here<br />
End Get<br />
Set(ByVal Value As DataTypes)<br />
'Your code here<br />
End Set

Thanks
Here it's not taking Date as a type of enum . Rising error 'at the place of Date
" Statement cannot appear within a enum body " .
|
|
|
|
|
Sorry, the example should have read :-
Enum DataTypes<br />
[Date]=1 '<--- Note the square brackets<br />
Text=2<br />
Number=3<br />
End Enum<br />
<br />
Property DataType As DataTypes<br />
Get<br />
'Your code here<br />
End Get<br />
Set(ByVal Value As DataTypes)<br />
'Your code here<br />
End Set

Dim CustomDate As DateTimePicker<br />
Public Overrides Function EditValue(ByVal context As System.ComponentModel.ITypeDescriptorContext, ByVal provider As System.IServiceProvider, ByVal value As Object) As Object<br />
CustomDate = New DateTimePicker<br />
CustomDate.Format = DateTimePickerFormat.Custom<br />
CustomDate.CustomFormat = "d-MMM-yyyy"<br />
CustomDate.ShowUpDown = True<br />
CustomDate.Show()<br />
Return MyBase.EditValue(context, provider, value)<br />
End Function<br />
Public Overrides Function GetEditStyle(ByVal context As System.ComponentModel.ITypeDescriptorContext) As System.Drawing.Design.UITypeEditorEditStyle<br />
Return UITypeEditorEditStyle.DropDown<br />

Does any body know how to change to height of the textbox?
Do we have to use any API's to do that?
Any idea or link??
|
|
|
|
|
Hello,
There is no option to change the height of TextBox in .Net. But,
there are other options using which you can change the height.
1. You can set the 'MultiLine' property to True. However, this will
cause the text to wrap into multiple lines.
2. Another option is to increase the font of the Textbox. This will
automatically set the height of the Textbox.
I hope this answers your query.

Hello every one
I am having a VB 2005 application and using “DrawString” to print a bill.
I want is to print the amount in floating point format, with decimal point like “56.00” instead of “56”
I am using floating points variables but when I am changing it into string, to sent it for printing “.00” will is lost
Also I wanted the numeric columns to be right aligned which I am not able to do
Can any one give me a idea how to do it..
Regards
Nishkarsh

Convert the value to a string format in the DrawString Method:
DrawString(Format(value,"0.00"),...)
This will ensure the format you want.

Thanks for ur help. It is working.
Any idea how to align the text to right?
The numbers I am printing for amount should be right aligned.
In case of DrawString i can just tell the starting, i.e. only the left most point. How do I do that?
|
|
|
|
|
To align the text you have to set up a StringFormat object:
Dim sf As New StringFormat<br />
sf.Alignment = StringAlignment.Far<br />
sf.LineAlignment = StringAlignment.Center<br />
<br />
DrawString(Format(value,"0.00"),fnt, Brushes.Black,rectF,sf)
(I cant remember if the LineAlignment and Alignment properties are around the right way but a little trial and error will sort this out.)
Cheers

To format a number as money use: YourDecimalOrFloatOrDoubleOrWhatEver.Tostring("F")
If you mean columns in a datagrid, you should explore the possibilities of the TableStyle.
