OK, you've got two options. Either launch a new copy of your program, closing the existing copy after the launch, or, you write your code so that there is a method that resets all of your controls and variables to their starting values. There is no single command that's going to do this for you.

Hi,
you could try and create a main form that remains invisible, and basically contains a loop
in which you instantiate and show a second form (your current initial form) until your
MsgBoxResult says "No".

Does anyone know how to redirect to a specific file. when i use response.redirect("default.aspx") it looks in the current folder. How do i redirect to a file in a different folder. I have tried the file location ("c:\websites\default.aspx")but does not work.
many thanks

You should post this in the ASP.NET forums.
Response.Redirect requires a remote path, not a local path, e.g. Response.Redirect("http://example.com/full/path/to/default.aspx") or Response.Redirect("../../default.aspx")
|
|
|
|
|
Youc can also try
Response.Redirect("~/default.aspx")
Ask not whether it is useful. Ask what it is useful for.

You can get a decent introduction to some SQL and parameterized queries here[^]. It's not a step-by-step "this is how you do it", but it does demonstrate how to run queries.
As for teaching you how to do this, it would take a small book to lay all this stuff out. That's far bigger than any series of forum posts would allow for...

I don't think this would even compile ? I think he's trying to call getdate in VB, when I told him yesterday it's a function inside SQL Server.

Yeah, it's not looking good at all. I'd scrap all the adapter stuff and just go with the hand written data layer since it'd be so small. But, as you've said, you kind of have to know what your doing in either case. Just because it's "drag'n'drop" doesn't mean you can use the stuff without knowing how it works.

It's "how", not "haw". And I have no idea what you're talking about with this statement.

As far as I can tell, there's nothing in the Mobile 6 API that will allow you to do this.

This App. (Pocket Max Redile.cab) can Auto Redile and Vibrating when Connected ... How it Done ???

I have no idea considering I don't do any mobile development. I just looked through the SDK documentation and didn't see anything that would suggest functionality like you want. I don't have any hardware to test on, so comming up with example code is impossible for me.
You might want to ask this question in the mobile Development[^] forum, since this has nothing to do with VB.NET.

I have a login form that opens the next form if the login is succesful. Is it possible to have the login window close when the next form is opened? Right now when I close the login form everyhing is closed. I know that it's because the login form is the parent of the new form..(at least i think this is why).
Is there a solution to my problem? Can I open a new form from the login without it being a child to it? or will i have to just hide the login window?
Thanks for any replies

It sounds like you might have the "Startup form" (in the project's properties) set to be the Login form and the "Shutdown mode" set to "When startup form closes." So then when the Login form closes, the application exits. If this is the case, change the "Shutdown mode" option to be "When last form closes."

Thanks! Now it works perfectly, i had to chuckle a bit though because of the simplicity of the solution.

Hello,
I wrote an application that use Micorsoft excel 11.0 (excel 2003). The application is used by ~50 users. The problem is that not in all computers is installed excel 2003 but instead office XP or 97.
The part of the application that is using the excel component crash in those computers. In there a way to add multiple references to different excel version? Something else to sove this problem.
My solution is to write 3 version of my application but is it very complicated essentialy when I need to update the program.
Thank you.

It sounds like your application is using early-binding with Excel - there is a reference directly to the DLL in the appication.
Can the application be rewritten to use late-binding and simply use whatever version of Excel is on the client computer?
Yes, this will probably required a great deal of work, but, it may also solve the problem.
I encountered a similar problem with Micrsoft ActiveX Data objects; my application was referencing a version higher than the end-user had available. So, I used a CreateObject call rather than define the object directly.

How can I create an instance of T in next code?
I have this code:
class MyCollection (of T)
inherits Collection(of T)
Public Function CreateInstance As Object
Dim obj as Object
obj = new ???????
...
end sub
end class
Sub MyMethod
dim obj as MyClass
dim adMyDictionary as new adDictionary(of MyClass)
obj = adMyDictionary.CrearInstance
end sub
My question is: How can I create a MyClass instance from CreateInstance method? How can AdDictionary class know the type of its elements during executing time?
|

Betelgueuse2 wrote: How can I create a MyClass instance from CreateInstance method?
Using the New keyword, as with any class:
obj = New T()
You have to stipulate in the signature of the MyCollection class that the T type is a class and that it has a parameterless constructor, though.
Why are you returning an Object reference from the CreateInstance method? You should return a T reference.
Betelgueuse2 wrote: How can AdDictionary class know the type of its elements during executing time?
I assume that adDictionary and MyCollection is actually the same class?
When using generics, the data types are all known at compile time, so the compiler will create code that handles the types that you use with the generic class.
Despite everything, the person most likely to be fooling you next is yourself.

Hi,
I am struggling with merged cells. If I have a single cell and the text is long, then when I check wrap text then the text is wrapped and the height of the line is increased. When I have 2 cells merged, and the text is too long, then it does wrap, but it cuts off, and the line height is not adjusted so that all the text is displayed.
How do I get this to work for merged cells the same as for single cells.

Hi,
I have a string with the following value:
"My String 123"
I have to search for "My String". What function do I need to use?
I am using VBA for Excel.
Brendan

|

Assuming you are using VB.NET, the following code shows the the use of the Contains method of a string
Dim myString as String<br />
myString = "My String 123"<br />
<br />
If myString.Contains("My String") = True Then<br />
'Do something<br />
Else<br />
'Do something else<br />
End If
