I am condemned for my sins to write in VB 6 for the next several whiles. Every time I fire up VS and select my project the IDE is populated with five modules I have absolutely no interest in seeing, editing, running, or anything else. I have closed them and saved the project more than once, but there they are the next time I start up.
Does anyone know where VS or VB saves whatever it is that makes these things appear?
Better yet, does anyone know how to make them stop appearing?
Thanx,
JimT

In the path that you save your project, delete all files whose extension is not as the known formats, e.g. if you have Form1.frm, then (if I remember correctly) Form1.frk or something like that is also created. Also one extra file is created with the name of your project, but without .vbw extension.
I can remember that if you delete these files, you would get what you want.

Thanks for your help. I tried it, but that didn't work either.
There were two files, as you suggested: .vbp and .vbw. I deleted the .vbw file and the annoying files quit appearing.
Thanks again!

I love the splitcontainer, but I need more than 2 panels. Any ideas of a good solution?
Thank you.
|
|
|
|
|
What about putting another SplitContainer inside one of the panels of the first SplitContainer?
|
|
|
|
|
Thank you.. yes, that is the way to go -- nest the splitcontainers inside each other.

Sorry, but I'm having trouble with what should be easy.
How to I detect that the user is holding down a key (F1 for instance) when the program first loads?
Thanks
|

Actually, it's quite difficult. Your application wasn't running when the key was pressed, so can't get a normal event notification that it was.
You'll have to use the Win32 API function GetAsynceKeyState[^] to find out if the key is still being held down. If I remember correctly, the virtual key code for "F1" is &H70.

Not hard at all actually... works perfect.. thanks!

 Most people can't figure out how to do P/Invoke, let alone the binary math on the returned value. Glad to see you're not one of them!
|
|
|
|
|
It's much easier than that:
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal KeyVal As Integer) As Integer
then:
Dim t As Integer = Me.GetAsyncKeyState(&H71)

Hi,
I am making a application which is communicate with another application on the same system.
i use config file for the remoting cofiguration.And its worked fine for few minutes.
But after some times an error is occured when try to raise event to the client from server. Error is "Object '/313ea683_ade8_4edd_9b25_d5a9566a83b4/st61eu4jxpjjvhgy1ts4zuuk_1.rem' has been disconnected or does not exist at the server."
I already to the lease to Time.Span=0 and also try Nothing.
But same problem is occured.
At the same time client is properly responding i.e. client is able to raise event at server.
can any one soultion for the same.please help about this??????????
Complete error message is -->

Hi
As far as i know every MarshalByRefObject proxy has a limited lifetime which is by default 5 minutes. if you call a method on the object, the lifetime is increased by 2 minutes.
so if you don't raise an event for 2 minutes on the client, the proxy that presents the client to the server will die.
you can solve the problem by
a) adding an ISponsor that keeps the proxy alive
b) setting the lifetime in the InitializeLifetimeService method and use a more appropriate initial lifetime for the client proxy.

thanks for ur reply.
But i already override InitializeLifeTimeService and set initializetime to 0 or nothing
So i think object should alive for the life time.
And if proxy object is dead, than how client can raise event at server.
Please do me fever...

We have to see the code you used to change the lease time. The lease, obviously, isn't being changed because it's still expiring.

i don't think the server is the problem. keep in mind that ANY MarshalByRefObject instance that is shared over remoting creates a proxy. so if your server can call a method on your client.
a) your client must be a MarshalByRefObject too (it'l create a proxy and everything...) so the problem might be that that proxy dies
b) i'm not sure if delegates are serialized or marshalled so there might also be a problem..
i'd suggest you take a closer look at the client implementation.

Hello
I'm working with Visual Studio 2005 (VB)
When I polulate a listview (details) with a large amount of data (100 lines) the screen goes blank while filling the listview. The same goes when I fill a list of custom controls.
Is there a way to avoid this ?
|

How are you populatiing your list? If you are looping through a collection of some sort, you could try using Application.DoEvents() inside the loop .

Hi,
if your app becomes unresponsive while populating a control, then runs fine again,
you should try and speed up the populating action, or use a background thread
(with Invoke stuff). If the GUI is screwed even when the population is done,
you probably violated the cross-thread-access rules for Controls (again, Invoke).
Speeding up can be obtained by avoiding the constant recalculations, due to the
fact the control cannot guess when the last addition will occur, so it relayouts
things all the time. Use Control.SuspendLayout() and ResumeLayout().
For Controls that have an AddRange, that helps too.
Using Application.DoEvents() is a hack: it lets your GUI settle but does not
shorten the population time, and it will fail dramatically if it ever is executed
concurrently (depends on where your population code is called).

hi,
I intend to implement a client-server model wherein a few clients are connected to a server. Allow the clients to have secure communication (chat and/or file transfer) using the SSL protocol.Tunneling would be the most important thing to be implemented in this project.What I want to know is,
1.Can I use the TAP driver used by OpenVPN to handle the transmission of packets?
2.If yes, how can I use the driver while coding?
3.If no, can you suggest any open source drivers for VPN?
4.How to implement the SSL protocol?
5.To show that secure communication is taking place,would sniffing the transmitted packets be enough?

You're going to have to ask the people who wrote OpenVPN these questions. I've never used their library.

Hi,

For which browser?
AshuVyas wrote: in vb.net
Possibly. You realise that the code has to run on the client? I.e. this can't be done in server side code in ASP.NET.
AshuVyas wrote: or javascript
Not possible. You have no access to the file system from Javascript.
Experience is the sum of all the mistakes you have done.

I can't seem to figure out how to get VB to recognize's any of the public key type's supported by PHP/OpenSSL. Any ideas?
