Why do you not store the path to the image file rather than the image itself?

I'm using ASP.Net 2.0. I need to show data from a single field (as a
hyperlink) but the column is to be repeated (RepeatColumns = 2). I have
this in a DataList control and it is working fine. There is an additional requirement now to add a pager control, but it seems like I would have to use a GridView instead of a DataList in order to allow paging. The GridView doesn't have the capability to repeat columns however.

Hi all,
I hv coded a function to convert a string to a particular DateFormat. It works well good.But when I pass the dt as 25-12-2007 , I am
getting the error as
Message "The string was not recognized as a valid DateTime. There is a unknown word starting at index 0." String
Function
Public Shared Function DisplayFormatedDate(ByVal dt As String, ByVal strDateStringValue As String) As String
Try
Dim dttemp As String
Dim strFormat As String = strDateStringValue.Trim
strFormat = strFormat.Replace("mm", "MM")
If Len(dt) > 0 Then
'dttemp = Date.Parse(dt).ToString(strFormat)
dttemp = Convert.ToDateTime(dt).Parse(strFormat).ToString
End If
Return dttemp
Catch ex As Exception
End Try
End Function
|
|
|
|
|
Replace
dttemp = Convert.ToDateTime(dt).Parse(strFormat).ToString
with
dttemp = Convert.ToDateTime(dt).ToString(strFormat)

Although I am not sure how you would have to go about it, you could for example program your app to only use the default printer and/or devise a method to check whether a printer is virtual or real. If it is real allow printing, and if not then disallow.
My advice is free, and you may get what you paid for.

Hi,
I have a form application (Form1) with contol1 (a Label) as an added control of control2(a panel) I tried to process the mousedown event in control2 when mousedown happens in control1.
I tried to use code like this
Label_click(...) handles control1.mousedown
RaiseEvent control2.mousedown(...)
it wont compile.. ;(
Any idea on how to do it?
Or even better, how to make control1 transprent of any event (possible?) so that control2 will directly see the mousedown event.
Is there any good book or tutorials talk about events handling?
Thanks a lot.

Why don't you just call the hanlder (or even better the sub/function doing your stuff) directly instead of trying to fire the event itself?
This is the way I normaly do this:
Write functions/subs to do your stuff.
In the eventhandlers just call those functions (a benefit of this is that you can implement your events with AddHandler and a anonymous function if you like - of couse you can do this anyway but the AddHandler line / block will get very crowded if you code everything there).

I need to modify the sizes of other controls in the panel based on the mousemove event. I think the mousemove events only provide the client coordinates, i.e. the coordinate inside control1, if the event is handled in the label. So I need to convert the coordinate, right? or there are better ways to do it?
More specific, I am doing width-resziable labels in the panel. I try to resize the label width with mouse... just like resize the colume within a table.
Thanks

I needed to make a change to the size of a field in an access database so that it would store a path to an image. The field was a text field with a size of 50...I changed it to size of 255 which is the max.
So now I cannot figure out what I need to update in my program so that it will pick up the new field size change. I keep getting an error that says I am violating the maxlength limit of the column.
Any suggestions?
Thanks

Did you save the change? Have you confirmed that the access database has the new size?
When you change the data structure, the code will automatically pick up the change, as long as you rerun the program and the connection is recreated.
Also, I would check the length of the path, which you are trying to save in the database.

In my VB.net application I want to make sure that only one instance of application is running at a time on a client computer. Furthermore I want to perform following tasks:
1. My application should accept a command line argument (Customer Id).
2. Pass this argument to already running instance of the application.
3. Search and load customer data from database and display the respected form in the existing instance.
I have managed to restrict multiple instance by using Process object and easily accepted command line arguments by using My.Application.CommandLineArgs collection.
Public Sub Main()
Dim tempProcess As Process
tempProcess = checkInstance() ' A function which validates current process
If tempProcess Is Nothing Then
Application.Run(New frmWelcome)
Else
Dim hwnd As Int32
hwnd = tempProcess.MainWindowHandle.ToInt32
Try
If hwnd > 0 Then
If IsWindowVisible(hwnd) = False Then
ShowWindowAsync(hwnd, ShowWindowConstants.SW_MAXIMIZE)
End If
SwitchToThisWindow(hwnd, True)
SetForegroundWindow(hwnd)
SetActiveWindow(hwnd)
LoadContact() 'A function which extracts command line argument and call a function from existing running instance.
Application.Exit()
End If
Catch ex As Exception
MsgBox(ex.Message)
End Try
End If
End Sub
When I call a function from existing instance I get an error 'Unable to create window handle'.
Basically I am not an experienced VB.Net programmer, I will appreciate if someone have a look into it and help me out. I will be very thankful if someone pass me an example.
Many thanks

Probably through using the System.Net namespace. You might want to try googling since there are plenty of examples out there and even on this site...

Maybe you could start with a reporting engine like Crystal Reports, or some of the other good ones out there. I leave it to you as a research exercise to google the other good ones

The Visual Basic Power Toys gave you a very simple printing method (like VB6).
And also search google with "printing vb.net" -> you will found enough to start.

Hi All,
I have done a project in VB6. The main EXE file and supporting files copied to USB drive. I want to give Copy protection for the USB.
I need to protect my application against illegal copying.
Please give some suggestion. Thanks
Thanks & Regards

Sure...good luck since copy protecting an app is a long and involved process that is out of the scope of a forum posting.

We sell a licensing library, but it only handles licensing and no further - copy protection is a long, involved, frustrating and eventually futile ball game (kindof like golf).
Hit up google for copy-protection libraries. Theres a few licensing libraries around that have copy-protection features - but I can't speak for their effectiveness.

VB.NET 2005
I have some toolbar buttons on my "main" form that i would like to access from another form
Somehow, I have not been able to figure it out ...
Inside the Main window I can use
DriveEnable.pushed =true (where DriveEnable is the name of the actual button in the collection) and that works (of course  )
In my module I'm using
Main.Drivenable.pushed =true .. but it does not work (no error either - just nothing happens)
I have set all "possible" properties of the toolbar tool / button(s) to Public - doesnt seem to help me ..
Whats the missing link ?
