No problem...
One word though... dependign on how modular you want to make your code you may want to check to make sure that you can actualy do the cast before you do it. That way if for some reason you happen to accidently patch that event hander to a different control you will catch that and not throw an excpetion. Maybe wrap the cast in a try/catch block or something.
You can do something like:
Private Sub ClickHandler(ByVal sender As Object, ByVal e as EventArgs)
If (sender.GetType.ToString = "LinkLabel") then
nCurrFileNum = DirectCast(Sender, LinkLabel).Name
strCurrFile = DirectCast(Sender, LinkLabel).Text
Dim webURL As New Uri(strDefaultPath + strCurrFile)
webMain.Url = webURL
Else
'Not a linklabel control.
End If
End Sub

have a windows application that accesses a oracle database. I need to
deploy it on an intranet. It is an application that will be access by several
end users. I would like to deploy it in one common place and let end users
execute the same exe thus making it easy it implement changes as they will be
needed. How do you deploy a winform application in this manner?
i've already build msi file and i am deploying on my server but it gives me error that shows unhandled exception.
and also it is running fine on couple of computer ..that i installed on them independently. it is running fine.

you should look into clickonce deployment. Basically all you need to do is right click on your project and click on publish.
There is a lot of info from Microsoft on this.

Any machine that the application runs on is going to have to have the Oracle 8i Client installed on them at a minimum. The Oracle provider in .NET can't work without it.

Hey Dave,
Thanks man.
yeah..every machine have oracle 9i installed . my question is The Oracle Provider for .NET is not installed on every machine. should i install on every machine or if only on server will be fine.
b/c several ppl is going to use this application.its tedious job to install on every client machine . pls. reply me as soon as possible.
i am stuck here with the deployment .
if you have any idea how to deploy my application on server then let me know.
actually what i did is..i ve added setup project in my solution. and built it. and create .msi file.
when i am installing on the other machine and if it has ODP (oracle provider for net) installed on that its running perfectly. but it doesnt have that then its gives me error: "TNS couldnt resolve the service name"
and i am using System.Data.OracleClient and have referenced to my solution.
i m not using DataAccess.dll
i've not referenced to this dll.
i dont have any idea.
If u can reply me.that will be great.
Thanks a lot..

It's part of the .NET Framework Base Class Library, so if the .NET Framework is installed, so is the Oracle Provider.
... Or are you talking about the ODBC .NET Data Provider[^]???
If your using this, then, yes, you have to install it on every machine that's going to run your app.

Greetings everyone!
Question! Is there a way to set up the installer of a VB.NET program that will you set a condition to evaluate that will give the user the choice of either creating a desktop shortcut or not?
Any help would be fantastic!
|
|
|
|
|
|
Unfortunatly no. When you create the shortcut via the file system editor, the shortcut you create does not have a place for checking the condition from one of the installation dialog boxes that I have seen unless I am overlooking something.
If all about are losing their head while you keeping yours, you must be the one holding the axe!

Visual Studio 2003 v7.1.3088
.NET Framework 1.1.4322 SP1
----------------------------------------
I have a large WinForms project.
I have a form where I added a checkbox chkIsEmployee.
Sporatically, I get errors:
'chkIsEmployee' is not a member of 'ClearView.SMS.frmStudentManagement'
However, all of the designer code appears to be intact:
...
[Line 133] Friend WithEvents chkIsEmployee As System.Windows.Forms.CheckBox
...
[Line 181] Me.chkIsEmployee = New System.Windows.Forms.CheckBox
...
[Line 346] Me.grpDemographics.Controls.Add(Me.chkIsEmployee)
...
'
'chkIsEmployee
'
[Line 371] Me.chkIsEmployee.Location = New System.Drawing.Point(222, 99)
[Line 372] Me.chkIsEmployee.Name = "chkIsEmployee"
[Line 373] Me.chkIsEmployee.Size = New System.Drawing.Size(92, 16)
[Line 374] Me.chkIsEmployee.TabIndex = 16
[Line 375] Me.chkIsEmployee.Text = "is employee"
...
Now, I open the form, and the checkbox control is visibly gone.
It is almost as though the compiler is ignoring line 133. All lines after 133 have the error - not 133.
I rebuild the app and sometimes, suddenly all is OK.
I have tried deleteing the checkbox and re-adding it. The problem keeps re-surfacing. It was doing this behavior on a different control before.
Later, I open the form, and the control is gone again, but all the declaritive code in the form is still there.
This happened to me before (in this project with a different form), and I had to create a new form, paste controls on, paste my code in, delete the old form and the behavior went away.
I tried that here, but the behavior keeps comming back.
Is anyone aware of a bug or a fix for this?
Thanks,

Yep, it's a bug in the IDE. Nope, there is no permanant fix for it yet. You've already discovered the only work around I know of. SP1 for Visual Studio 2003 should be comming out sometime last month. 
Oh! Have you installed SP1 for the .NET Framework 1.1?? If not, get it from here[^].

Hi,
I've been surfing the web for the following question, with no luck. Do you know of any solution regarding having a parent form (MDIparent) calling a DLL and the DLL will be known as child to MDIparent?
Looking forward hearing from you.
Kjartan Þór Guðmundsson
|
|
|
|
|
Your question doesn't make any sense. I .DLL cannot be a child of anything, except a process in a round-about way.
Is this .DLL supposed to be returning a Form? Without any details about your .DLL, there's really not much anyone can do to help you.

is the DLL a separate user control with a form?
|
|
|
|
|
Sorry about the unaccurate question. The DLL is a form, I'm building a large project and have no intention to have in one project.
Kjartan
|
|
|
|
|
This form is it's own class library?
Then all you would have to do is create an instance of it, just like any other form:
Dim newForm As New MyDllForm
newForm.Parent = Me
newForm.Show()

I get this errormessage.
An unhandled exception of type 'System.ArgumentException' occurred in system.windows.forms.dll
Additional information: Cannot add a top level control to a control.
Kjartan

|
|
|
|
instead of newForm.Parent = Me, which gives an error, you should have
newForm.MdiParent = Me, and then it works fine.

Hello,
I have a filestream that I am able to read only once when my program launches. If I attempt to read the line a second time, I receive the message "The process cannot access the file 'C:\IMGfromDB.BMP' because it is being used by another process." at this line of code...
fs = New FileStream(savedIMGName, FileMode.OpenOrCreate, FileAccess.Write)
I've tried the following to release the processes...
fs.Close()<br />
fs.Dispose() and
File.Delete(savedIMGName)
Thanks in advance
