The Date Picker control was hard coded using CreateWindowEx(), using the class SysDateTimePick32 and I can only set its properties using SendMessageSTRING(). So I cannot perform your suggestion.

Have you tried nishkars suggestion in combination with
Private Const DTM_SETFORMAT = &H1032
In other words, have you experimented with assigning some other value than "&H1032" ?
What happens when you enter a string like "dd/MM/yyyy", or something similar ?
My advice is free, and you may get what you paid for.

Hi I know now where the problem was.
DTM_SETFORMAT should be &H1005.
I looked it up at commctrl.h.
My mistake. I just copied the previous value somewhere in the internet.

Hi all,
I have an option to select all records of checklistbox.
Is there any way to select all the records of checklistbox without making the loop iteration?
Thanks

AFAIK you have to use a loop, unless there is an API call call that can be used. All of the relevant properties have get accessors only.

Hello every one.
I am having a Vb.net 2005 Express application. I want to have a log of all call stack which will enable me in improving the performance of the application.
Is there any way I can get it without inserting a line of code in every function to write in the log
Regards
Nishkarsh

You need to read up on Artificial Intelligence. Basically you can hard code some rules for the game to follow, or write a system where the more you play, the more it learns how to win. No-one is going to explain how to do this in a forum reply.

Heuristic programming is a subject all to itself!
Mobile phones employ it on the predictive text, so do intelligent computers that run interplanetry craft which come across black monoliths.
I suggest the Stanford work is best for you.

Sounds like you have absolutely no idea what you're doing.
You could use terminal services to connect to a server running your app. That's about it really.

you can not connect to windows application remotely, unless it is a client/server application. Even with that, only you can interact to the server from the client.
You can connect to a remote machine then use the application. but this has nothing to do with application. There are several ways you can connect to remote machine, Remote Desktop, Terminal Services and connection over the web.

This is low speed to connect and work remotely.

I'm setting up a card game; solitaire, and I want to drag one card on top of a bitmap that looks like a blank card. I want the card image to stay on top IF it matches a certain variable (array of an image). I have the source images as Image1(52) array of cards, and the target images as Hearts(12). I will do Clubs, etc., but am just starting with hearts suit to test. Here is my code so far. I'm having difficulty on trying to figure out how to drag the image and copy it on top of another image if it equals that image's properties (array #).
Private Sub Image1_DragDrop(Index As Integer, Source As Control, X As Single, Y As Single)
Index = 12
If TypeOf Source Is Image Then
Image1(Index).Picture = Source.Picture
End If
End Sub
Private Sub Image1_MouseMove(Index As Integer, Button As Integer, Shift As Integer, X As Single, Y As Single)
Index = 12
If Button = vbLeftButton Then
Image1(Index).Drag vbBeginDrag
End If
End Sub
Private Sub Image1_MouseUp(Index As Integer, Button As Integer, Shift As Integer, X As Single, Y As Single)
Index = 12
If Button = vbLeftButton Then
Image1(Index).Drag vbEndDrag
End If
End Sub
Any ideas would be appreciated.

A two-step implementation for drag'n'drop;
- Start the dragdrop operation by calling the DoDragDrop method in the MouseDown event.
- Set AllowDrop to True for the control that you're going to drop things on.
MSDN has dedicated a page to the topic Drag&Drop in VB.NET[^]

Thanks, but I'm doing this in VB6, not .NET. So, it is another name for the method. It won't take the parameters you gave me.

Thanks, I read this and tried with basically I have an array of cards in design view; trying to drag one of those cards to another array of cards.
Image1(12) to Hearts(12) as an example.
Trying to drag over an icon already in the Hearts(12) position and drop on that icon "after" it equals the value of the card. Kind of weird how I'm doing it, but I wanted to have a visual blank picture of a card in white, and the let's say, hearts King card either underneath hidden or be the same value as the white card. Then when the hearts King is found on the left, it gets dragged and dropped if it matches the king card on the right. I hope I make sense.
Having problems with the array. Compiler won't accept Hearts(12) or Image1(12); says it needs an identifier, so I tried this an it doesn't work. Any ideas would be much appreciated. Thanks in advance.
Private Sub Image1_MouseMove(Index As Integer, Button As Integer, Shift As Integer, x As Single, y As Single)
Index = 52
Image1 = Image1(Index)
If Button = vbLeftButton Then
Image1.Drag vbBeginDrag = 1
End If
End Sub
Private Sub Image1_MouseUp(Index As Integer, Button As Integer, Shift As Integer, x As Single, y As Single)
Index = 52
Image1 = Image1(Index)
If Button = vbLeftButton Then
Imag1.Drag vbEndDrag = 0
End If
End Sub
Private Sub Hearts_DragOver(Index As Integer, source As Control, x As Single, y As Single, State As Integer)
Index = 12
Hearts = Hearts(Index)
Hearts(Index).Picture = source.Picture
State = 0
End Sub
Private Sub Hearts_DragDrop(Index As Integer, source As Control, x As Single, y As Single)
Index = 12
Hearts = Hearts(Index)
Hearts(Index).Picture = source.Picture
End Sub

That error is thrown in the _DragDrop, on the line below?
Hearts = Hearts(Index) What type is the left "Hearts"? Is it a PictureBox?

|

|

Starts with Image1(index). I don't think I can make Image1 = Image1(index); an array. Maybe I can just use the Set command?
Let me explain more;
On the left, in design view, I have 52 images of cards in suits. I shuffle them when the start button is pressed. Now, I want to move any of the bottom cards on the left to positions on the right. On the right, there is, let's say, 13 cards of Hearts suit. There is an image on them, not a picture box. Just an image of blank cards. I want that so the player will see where to drop a card. If the card doesn't match the card on the right, then it cannot be dropped there, and basically flies back to it's position on the left, where the player can only put that card in, let's say, a holding area and drop it there for use later. It is solitaire, but played a different way.
Hope this helps....
Thanks in advance.

Silly me; I figured it out. This works....
Private Sub Hearts_DragDrop(Index As Integer, Source As Control, X As Single, Y As Single)
Index = 12
If TypeOf Source Is Image Then
Hearts(Index).Picture = Source.Picture
End If
End Sub
Private Sub Image1_MouseMove(Index As Integer, Button As Integer, Shift As Integer, X As Single, Y As Single)
Index = 12
If Button = vbLeftButton Then
Image1(Index).Drag vbBeginDrag
End If
End Sub
Private Sub Image1_MouseUp(Index As Integer, Button As Integer, Shift As Integer, X As Single, Y As Single)
Index = 12
If Button = vbLeftButton Then
Image1(Index).Drag vbEndDrag
End If
End Sub

i have searched the internet for a windows explorer like app code, and mostly it is to use a treeview and listview on your form. the code included is so complicated, i don't know where to start...
if possible, i would like something like so:
1.load the the directory folders and the folder files, (2 separate controls)
something simple like, onload, load control 1 & 2
2. when i click the folder directory, the file directory to change as supposed. again, something simple.
3. open file on double click in whatever default app. it is set to open in..
THE CODE SHOULD BE ABOUT AS LONG AS THIS POST..
thanx in advance, since i've been having trouble getting this together for a while, and i just want a windows explorer project, (since i use it quite often), to make it easier to navigate my file locations.
i have came across using the webbrowser for file searching, which works great, but does it slow down the pc to have 4 or 5 of them in a tabcontrol. personally i don't think it should, but i'm not the expert here.

if it all is simple, and as short as your post, then why didn't you just write it, instead of your post?
Anyway, people aren't going to create it for you, so I suggest you search here at CodeProject, or use Google.
