I suspect you need admin rights to lock the desktop, but you would be better off contacting the dll vendor to check this.

Hi friends,
We use SAP dll's (librfc32.dll v6405.5.162.5282, librfc32u.dll v6405.5.162.5281, ...) to open a connection to SAP server, but if server can't response us we used to wait for a while (60 sec).
Can we decrease this connection (logon) timeout to a lower constant (10 sec).
Does anyone know how to set this logon timeout?
Thanks for your help.

You'll probably have better luck finding an answer to questions related to SAP products here[^]
If you have access to the SAP Service Marketplace you should be able to request a user ID for the developer forums.
Good luck,
Johan
My advice is free, and you may get what you paid for.

Hello
I have the following code that draws a rectangle in panel. Now I want that when I click a button I draw the rectangle in the panel. Can any one help pls.
Thank you
Imports System.Drawing.Drawing2D
Public Class Form1
Private Sub Panel1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Panel1.Paint
Dim g As Graphics = e.Graphics
Dim rect As New Rectangle(50, 30, 100, 100)
Dim lBrush As New LinearGradientBrush(rect, Color.Red, Color.Yellow, LinearGradientMode.BackwardDiagonal)
g.FillRectangle(lBrush, rect)
End Sub
|
|
|
|
|
Call Panel1.Invalidate() in the click event of the button
|
|
|
|
|
You may use a Boolean variable and set its value on button click, in paint event of panel keep the same code however just check for value of this Boolean variable before drawing the rectangle.
Such as –
----------------------------
Private Sub Panel1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Panel1.Paint
If flag=True then
Dim g As Graphics = e.Graphics
Dim rect As New Rectangle(50, 30, 100, 100)
Dim lBrush As New LinearGradientBrush(rect, Color.Red, Color.Yellow, LinearGradientMode.BackwardDiagonal)
g.FillRectangle(lBrush, rect)
End If
End Sub
-------------------------
In case if you are going to draw more than just one rectangle in that panel, you may use an array of rectangle to draw multiple items on panel.

I am modifying a driver (DLL) that is written in VB6.
One of the modifications requires me to do a checksum check on all received data.
Here is the CRC Calculation Specification[^] which is unfortunately Greek to me (and seems to CP members also from the response I've been getting  ). Mostly because my C coding knowledge is almost NULL and my ASM is very rusted.
The resulting CRC value is a string of 4 hexadecimals e.g. "1BF2".
How should I go about doing this in VB6?
Kind Regards

Feel free to do so,  I only put that there for some of those fiercely territorial CP members that have nothing better to do than hang around in the Lounge all day and criticize other people's posts, they really get under my skin!
Anyway, thanks for the code, at least now I now what I'm looking at (CRC16), I'm going to give it a shot tomorrow and let you know!
Thanks again!!

Hi There
The code didn't work but with some tweaking and re-inventing the square vb6 wheel we got a working Checksum calculator which worked with data supplied.
Thanks again!!

Hi All,
In database I have two columns ParentCust and ChildCust.
I have a tree view.
Now I want to convert the tree view data in the dataset. I have a dataset in which I have these two columns as ParentCust and ChildCust.
How do i do that. A code snipet will be helpfull to me.

Hi All!
Still working furoiusly hard on my JavaScript Editor, and doing quite well now that i have overcome a few obstacles, however i have been sent tumbling head-first over yet another.
In VS, I have never ceased to be amazed at the intellisense, autocomplete and error-marking (Little squiggly line under bad peices of code). How would i go about implementing roughly these features, though obvoiusly scaled down a bit, for javaScript.
I Am Using SharpDevelop's TextEditor Control for my code editor control and so need any Intellisense to be compaitable with this control.
Thanks!

Maybe this[^] would be useful? As long as your TextEditor control has a OnKeyDown or simliar event that handles a key press that article might work.

Hi and Thanks!
The Link provided an excellent insight into how to begin to implement intellisense in my application, however it was not for javaScript, and from the looks of it can not be tweaked to accept javaScript.
Can anybody recommane a more database-oriented approach, perhaps using a database to fill out the intelliSense list?
Thanks Again!
MrWolfy

Hi MrWolfy,
I may not know exactly what you are looking for, but you can modify the code in that article to accommodate whatever intellisense you want. You could make the intellisense in a database and use that code to read the database (instead of calling readAssembly). Sorry if I misunderstood or if I'm telling you old news.

Hi!
Wow, you're right! Sorry, I Didn't understand at first but now I do! Thanks, you've been a great help!
Thanks Again!

It's possible to specify that a generic class will only accept items which meet multiple qualifications. For example, the class could be specified as working with Control objects which implement the iEnumerable and iSuperMagic interfaces by declaring it as something like
Class Whatever(of {Control,iComparable,iSuperMagic}). Is there any way to specify that method arguments and return values, class fields, etc. should likewise possess multiple qualities?
It would be possible to ignore the interface requirement in the definition and use typecasts to make the necessary calls (e.g. have a method accept an ordinary control and then use a typecast to use other interface methods or properties, e.g.
if ctype(iComparable,theObject).Comparer > 0 then but that seems like rather a kludge, and it would also delay until run-time type checking should should in many cases be possible at compile time.
Is there some workable syntax to produce complicated types that I'm simply not seeing? I've tried many variations of the "brace" notation and can't get it to work.

I am not sure I fully understand, but I am sure the answer is no. You define a method when you write it. Why would you define something abstract about what it's properties are, when you are about to define them concretely ?

Please read this if you don't understand the answer I've given you. If you're still stuck, ask me for more information.

In VB.net, it is very common and useful to be able to have classes which can operate on objects without knowing exactly what they are. For example, the Array class includes a Sort function which can operate on arrays of any type of data, provided only that they implement the iComparable interface. The code for Array.Sort doesn't care what it's sorting--all it cares about is the fact that the things it's sorting know how they compare with each other.
Suppose I want a container control that includes a function to auto-arrange its contents in sorted order (assume all child controls can be compared with each other and sort nicely). The control doesn't care what the child controls are, beyond the fact that (1) they must implement the iComparable interface, and (2) they inherit from System.Windows.Forms.Control, and thus possess the position and size properties necessary to arrange them.
Most existing controls would lack an iComparable interface, but any inheritable control could be made to support it. On the other hand, I don't know how to very well specify that the contents of the container must be controls that implement the iComparable interface.
I suppose it might be possible to define an interface called iComparableControl, which inherits iComparable and includes a method myCtl which returns an object of type Control (the idea would be that a control would return itself) but that would seem rather goofy. It would be much nicer to simply specify that the container held objects which were inherited from type Control and which implemented the iComparable interface.

So you want Sub Test(ctl As {Control, IComparable})?
There's no way to define a method like that.
In some cases, you might be able to use a generic method
Sub Test(Of T As {Control, IComparable})(ctl As T)
but unfortunately, that isn't always possible - e.g. you cannot have a List(Of {Control, IComparable}), as using generics for that would always limit you to a specific T.

I don't think I'd ever noticed a method coded like that--only classes and interfaces (and I never really understood how the latter worked). I'll have to think about whether that's sufficient, or whether it will be better to define an interface which returns a control (which in most cases should just be an item returning itself). I can see advantages both ways.

I have been looking for a program that will dial an office extension and then play a MP3 or WAV file (prefer MP3) and then hangup on a specified time interval. I have yet to find this so I have been looking into possibly creating one myself. I have limited VB 2008 Express experience, but i have looked over a couple of the TAPI examples but they do not cover the timing or the MP3/WAV playing. The following are the components of the program. I do not know how to do the timer or the TAPI programing to play the file over the phone, so any help would be appriciated. Thanks.
TextboxExt = Extension #
TextboxTime = minutes between dial/play
TextboxMP3 = MP3/WAV location
CmdButtonPlay = Manually dial/play, stop timer
CmdButtonStart = Start timer for playing, repeat until stopped
CmdButtonStop = Stop timer
LabelTimer = When timer is started, count down time until next dial/play (min/sec)
