Hi all,
I was wondering if it is possible to have a custom tree view with three check boxs beside each node(right side if possible) which have events attached to them. What I had in mind is somthing like this
-MainTitle
|----Child [] [] []
|----Child [] [] []
|----Child [] [] []
|----Child [] [] []
I am only new to VB.NET, so I'm not sure if this has been done or even can be done.
Thanks,
Nathan

It can be done. It would take creating an entirely custom control to do. This is not something someone new to VB.NET would normally be able to do.
For an example of a custom TreeView control, look at this[^] and see if you can follow it.

i am using crystal reports (the inbuilt tool of visual studio 2005).Is there any option which loads the reports with less access time.
|

hi sonia,
i have also face this problem. This problem occurs only first time because this time files(related to crystal report) load into the memory so next time reports loads quickly.
one option is load crystal report at startup of your application(take care of visiblity of your report at startup) so next time when you load a report , it takes less time.
Hope this helps

up till now, i don't found solution to this problem. one option is load crystal report at startup but from this option startup takes long time.

There is no solution. What you're seeing is the time it takes to startup the Crystal Reports runtime. There is simply no way to get around this.

So you are going to develop an ERP solution. Are you freelancing or working for a company? Any way I dont think you might get help here because logics of ERP solutions are always kept secret.
Any way best of Luck

I am working for one company.
I have already created the prjoect whcih is almost over.
I just want to confirm if something etc can be added in the purchase module.
Anyways thanks for reply.

You can actually go through a couple of open source ERP solutions which might guide you further. I know of a Java based open source ERP (Compeire right?) that is good.
|
|
|
|
|
Yes i was just going through same.
I have downloaded it and installed enterprisedb database also.
After installation of database when i try to install Compeire then it asks for some confuguration and In the system password it gives me error,
Error JDBC Connection and then my database name and location?
Wt could be the reason?

I am working on a game that requires knowing the distance between two objects on the screen. In other words point 1 and point 2 put into a function and the radius of (or actual distance between ) the two points returned by the function. Game pieces need to be able to calculate their "close neibors" and their "far neibors" for my program to work correctly. So far I've sent in point 1 to a function that returns an array of points that make up a circle. I then use the circle returned to try and calculate whether point 2 is inside or outside of the circle. This method is a mess and is not very accurate most of the time. Since VB.NET doesn't have a neat function for this like rectangle.contains(point) I'm a little lost because my geometry is very very rusty. Can somebody help me with a simple and quick function for this?
Thanks.

Hi Dan,
Perhaps you should consider forgetting the idea of areas around the game pieces and think more in terms of distances.
In other words, only determine the distances between all pieces, subtract their "personal space" from these distances, and you end up with which is (too) close and which (too) far.
This way you also do not need to store a whole lot of data in memory that you won't ever even use. Instead you only get two values per game piece: position and personal space.
The following function may be of use to you:
<br />
Public Function RoundToSignificance(ByVal number As Integer, ByVal significance As Integer) As Integer<br />
'Round number up or down to the nearest multiple of significance<br />
Dim d As Double<br />
d = number / significance<br />
d = Round(d, 0)<br />
RoundToSignificance = d * significance<br />
End Function
With it you can determine for instance in which direction a game piece should preferably (not) move.
Frappydan wrote: calculate whether point 2 is inside or outside of the circle
If the idea is to make a game piece react when another game piece comes within its bounds, you simply look at the distances after a piece has moved. This way it is also much easier to take into account special rules areas or obstructions, and such.
Hope this is of help to you,
Johan
My advice is free, and you may get what you paid for.

If you know the coordinates of the objects you can work out the magnitude of the displacement (vector)
formula is:
|vector| = sqrt((x*x) + (y*y) + (z*z))
so the vector would be pointA - pointB.
Hope I have understood you and that this helps.
this is a quick post as i am in a rush so i may have missed something out - post again if i have not been clear.
Thanks
Dan

I have a doubt regarding the Center Screen property of a form. When creating a application, I set the centerscreen property to 'CENTER'. But can I assure that this form will be displayed in the center of any monitor in the client side? I read in an article that this is an issue which the developers wouldn't even think of. So I just wanted to clarify it.
Thnx for any help.

Is there any property called centerscreen? 
The property is StartPosition, and if you set it to centerscreen than you will always have your application started in center of screen, no matter the monitor type/size.

Hi All,
I have vb code in the form of temp.bas file.
I want to use that in my VB.NET workspace.
Can any one tell me how to do this?
Thanks in Advance

Does it contain VB.NET code ? If not, you won't be able to use it.

VB.net does not support bas files. The replacement is the .Module file.
In a new VB.Net project, just add a new Module and paste your code into it.
However, it will probably not compile. VB.Net is rather different from VB. So, check the Errors tab, it will tell you what needs changing.
In the long run it would be best to rewrite your code as a class library, as VB.Net is an object orientated language, and module files are just an excuse for those who can't be bothered to upgrade their coding skills. .Net has been around for five years now!
If you have knowledge, let others light their candles at it.

Thank you very much for response.
The *.bas file contains VB code.
When I copy *.bas file content to my VB.NET workspace *.vb file and compile it shows many error.I am not able to resolve those error.
Is there any otherway we can compile *.bas file and use it VB.NET.
I dont have previous version of VB, can you please tell me how to compile *.bas file to generate exe and run it has standalone utility?
Thanks in Advance

Without the VB6 compiler, you're stuck. You don't have anything that will compile that code.
VB.NET will NOT compile a VB6 file without translation. Most of the old VB language is intact, but there are glaring differences in some of the basics. For instance, the Long type in VB6 is now an Integer.
You simply have no choice but to rewrite the code in VB.NET if you want to use it in your app.

Yes, you can get a copy of VB6 on ebay, and you can build a COM dll which your .NET app consumes. This is a really bad idea, you should rewrite the code. If you don't have VB6, where did the code come from ?

Hi All,
Thank you very much for all your help..
I think its good idea to rewrite the code in VB.NET.
Thank you all
