This dialog is implemented in the CommonDialog Windows control. You can add reference to the ComDlg32.OCX object in your script and use the methods in this object to Open / Save files. This will bring up the familiar Windows file dialog.

Beautiful, I will try that tonight. If its not too much to ask, I have another quick question:
This way of doing it leaves an extra cariage return at the end of the file, i tried writing a \b to the file once it is all done, but it literally writes a \b in the file.
Print #FileHandle, "\b"
Print #FileHandle, '\b' isn't a command as the ' starts a comment.
Is there a way to kill that last cariage return?

The Print statements appends a CR+LF to the text... I don't know of a way you could suppress this.
|
|
|
|
|
hmm, ok, thanks anyways!!
I'll play around with it and if I figure something out I will post it here.
--Its not broken if it never worked.
|
|
|
|
|
Put a semi-colon on the end of the Print statement.
Print #FileHandle, "something...";
This will avoid adding a CRLF to the end of the line it just printed to the file.

Hey hey that did it!, however because i am writing to the file inside of a loop there are no line breaks now. Is there a command I can put at the beginning of the string being written to the file to tell it to create a new line?
--Its not broken if it never worked.
|
|
|
|
|
Actually, never mind, i re-worked the loop to work around it.
Thanks a bunch everyone!!

Hello Friend!
I've built a windows application.
now I want to show any gif image while system is busy to save data in data base. after completing save operation the image will be invisible. again it will be visible during saving data.
How can I do this?
Please, help me.
Thanks!!!!!!!!!!

Use a Gif image in a picture box control, this will give you desired result.
Logic would be like this –
-----------------------------
Picturebox1.image=Image.FromFile(“OneAniImage.gif”)
SaveSomeData()
PictureBox1.image=nothing
------------------------------
I hope this helps.

i used this logic
but the result is that- after completing the whole task i.i, saving data, the image is displayed

Hi,
when you modify GUI elements (Controls) inside an event handler running on the GUI thread,
the result will show only when your handler is done.
Hence the sequence show_image, save, hide_image will NOT show an image.
There are basically two remedies:
- split the sequence using either a timer (not recommended here) or a thread or
backgroundworker; this is the recommended approach
- if you are sure your handler is not reentrant (will not be called again while
running) you could include a Application.DoEvents() to let the GUI settle
before continuing with the handler's execution. If you abuse it, side effects will
hit you, with a possible stack overflow.
BTW: don't cross-post, ask your question on one forum only!

I'm invoking COM dll method from VB program.
COM interface method takes one of the parameter as IUnknown as below
HRESULT SetMethod([in] long samNumber, [in] IUnknown* List);
When i try to call this method from VB by passing "null" as the second parameter i get error "424 Object required."
I dont want to create a new object. Why can't i pass null as the parameter? Is there any other way without creating object? Please help

Because the function won't let you??

Probably not, but that's up to the function you called. Without seeing the docs on this function, it's impossible to tell you what you can and cannot get away with.

Sir,
I developed an application in .net and java using corba.
My server is sun java jdk1.4.2 in linux platform.
My client is vb.net application in windows.
To link this i used iiop.net which generates a dll of the idl file .this idl is added as
reference to .net program.
I start the naming service as orbd -ORBInitialPort 1050 and then run the application as java AdderServer.
The server gets started and when I run the .net application it gives an
error message like this:
Error: omg.org.CORBA.TRANSIENT: CORBA system exception : omg.org.CORBA.TRANSIENT [Unable to connect to target.] , completed: Completed_No minor: 4000

The code for connectivity in .net is
Private Sub StartServerToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StartServerToolStripMenuItem.Click
Try
Dim nameServiceHost As String = ipAdd
Dim nameServicePort As Integer = 1050
Dim channel As New IiopClientChannel()
ChannelServices.RegisterChannel(channel)
Dim init As CorbaInit = CorbaInit.GetInit()
Dim nameService As NamingContext = init.GetNameService(nameServiceHost, nameServicePort)
Dim name() As NameComponent = New NameComponent() {New NameComponent("Adder")}
adder = CType(nameService.resolve(name), Adder)
nameService.resolve(name)
Me.tbl_server.Text = "Client connected to " & ipAdd
Catch ex As Exception
tbl_server.Text = "Error: " & ex.ToString()
End Try
End Sub
This is working if i run the client and server in two windows machines.
Waiting for u r reply.
Yoursfaithfully

Hi,
I have the problem in a larger project, however, even a simple windows program like a hello world prog leads to the same problem:
In Visual Studio.net 2005 (+VS2005-SP1, + all update as far as update.microsoft.com presents them) I created a new windows project in Visual Basic. It has one form and the form has one button. The code of the form reads:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
MessageBox.Show("Button has been clicked")
End Sub
End Class
It looks like a "hello world" program . When I compile it in debug mode (with "Any CPU") and start it it shows the form with the button and a click on the button shows the messagebox. So far everything works fine.
However, when I set a break point in the line >>MessageBox.Show("Button has been clicked")<< and compile it in debug mode (with "Any CPU") and start the prog, a click on the button does not start the debugger at the break point (as I would expect), but rather causes a program crash with the message "Test_Form.vshost.exe has detected a problem and must be quit." (this my translation of the German message I get: "Test_Form.vshost.exe hat ein Problem festgestellt und muss beendet werden."); "Test_Form" is the project name and assembly name.
I recently switched from VS.net 2003 to VS.net 2005. I never had a problem like this one in VS.net 2003.
What could cause the program crash? Help is very much welcome.
Michael

Do this happen in every project you try or just in this one project??
|
|
|
|

I have the problem in every project.
First I thought something in my large project I work on is wrong.
Then I was happy that I could boil the problem down to even simple projects like the "hello world" example I mentioned in detail. I tried other projects as well. The problem is always the same: a break point in the code of a click event results in a program crash when I click the questionable button.
Best wishes from Germany

About the only suggestion I have is to uninstall VS2005 and reinstall it.
|
|
|
|
|
will give it a try.
It's VS.net 2003 plus Update for VS.net 2005. It really takes a while, but I guess it's worth to be checked out.

Finally I've found the solution:
The firewall caused the problem. I posted the details in the following forum:

Hello Friend,
I've faced the following problem related to timeout.When I am going to save something large value in sql server 2005, following message is displayed.
"Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached."
Please tell me the solution.
Thanks!

Try increaing the connection timeout and query timeout on the connection. That should do the job. You should also see if you can improve the performance of your sql code.

I've written following connection string
gConnectionString = "Integrated Security=SSPI;trusted_connection=true" + ";database=" + database + ";server=" + server + ";Connection Timeout=1200;";
Is n't enough?
|
|
|
|

Are you closing your connections when you are done with them? If you don't close the connection they stay open until the garbage collector gets the connection object. If that happens it is very easy to run out of connections.
Also, why are you asking this in the VB.NET forum - there is a perfectly good C# forum when your question is about C#.
