View 1 RepliesI don't know what this is called so I've struggled to find an answer from google but I have a vague memory of it from t'old days.I've sub-classed (* see below) about 8 framework controls, overriden some properties and added some functionality into each one.The changes I have made are identical in every case. If I make a change, I have to go through each class and apply the same change there.I was hoping there may be a keyword such as <IncludeSourcefile "common.vb> that I can put into each class.
(* note) I use the term sub-classed but I don't know if that's the correct terminology. I've also seen it used for call-backs. Is sub-classed the correct term to use?

I have a two forms with about 25 bound controls on each in the same solution. All of the data for both forms is in the same SQL table. I need to filter the data and only get the data appropriate to the called form. I consulted an University VB professor and he would only say "it won't be easy".
I tried removing all of the bindings and rebinding them to the new datasource but there were still some remnants (probably from the navigator) that proved illusive.
Is the only solution to recreate the VB forms and bind them to the new datasource?

I've got a function that's supposed to extract and return a 32x32px bitmap from a larger bitmap which has a set of 32x32 tiles inside it.
Here's the code I have now, but it's wrong since the Tile.GFX_Pos properties are telling it where in the destination image to draw, not where in the source image to draw from.
Overloads Shared Function TileGFX(ByVal SrcGFX As Bitmap, ByVal Tile As TileDef) As System.Drawing.Bitmap

View 3 RepliesI have a WPF 4 and VB.net 2010 project. I am playing videos in a single mediaelement. This is what I need to do:When the window first opens, I have the first video play just fine. However, it is after this video plays that I run into trouble figuring out how to do the following.I need the video source to change immediately following a single play through of any video, and I need this video (henceforth referred to as an "ambient" video) to loop forever.When a certain event happens, I need to change the video source again, have it play once through, and then go back to looping ambient video in step 1.Here is the rub, however. Many of the video triggers are inside of If-Then or Select Case statements in code behind, so I'm not exclusively using simple WPF events such as "MouseUp" or "MouseEnter".Also, all videos must play in the same mediaelement, for performance reasons.

View 2 RepliesI think that changing from WinForms to WPF just because the blur effect is easier to do in WPF is the stupiest thing i can do right now it took me time to understand how the windows form application works i dont even how change the source of an image in WPF so here we are again. how to blur a speciefied image using CODE ONLY ?
See what im trying to do:
1. Imagine that you turn on your pc. takes some time to load.
2. Finally for the first time you are on the desktop.
3. Before you do something after every icon is loaded my program
takes a picture of the desktop and blurs it.
4. then it runs fullscreen showing the desktop behind as blurred and
not giving you access to the desktop.
5. a login/register border pops up
6. if you login the program closes if you dont it stays there
waiting for you to login or register.
I wont use it that way im planning to do it on the startup of my program only blur the window not the screen (i mean the content of my window) untill you login or register then it clears again. What i need to learn:
1. How to take a screenshot of my program (only yhe content of the window) [Progress: 1% (cause i know how to take a screenshot of the desktop)]
2. How to blur that image [Progress: 100%]
No need for third party programs or dlls i mean isnt there a default function in vb.net the stupiest way to do it?

I'm using a MS Access 2007 database. I modified the field definition of one of the fields in a table, it a text field and I change the maximum length from 40 to 150. I have a data source in my app that contains this table and many others. I refreshed the data source but the change didn't take affect. I went through configure option but the change still didn't take affect. It gives me this error,
The value violates the MaxLength limit of this column.
If I add/delete a database field the data source is updated when I go through the configure process. I finally just deleted the table from my data source and then added it back.

ive been trying to use System.Security.Cryptography to encrypt and decrypt a file but its not working for me
this code
Private Sub EncryptFile(ByVal sInputFilename As String, ByVal sOutputFilename As String, ByVal sKey As String)
Dim fsInput As New FileStream(sInputFilename, FileMode.Open, FileAccess.Read)
Dim fsEncrypted As New FileStream(sOutputFilename, FileMode.Create, FileAccess.Write)
Dim DES As New DESCryptoServiceProvider()
[code]....
called with
DecryptFile(OpenFileDialog1.FileName, SaveFileDialog1.FileName, "12345678")[/CODE]
outputs a file that is almost 2x as large as the source file that was encrypted.
In my program I allow the user to copy a file from one folder to another. If the file already exists in the target folder I want it to be overwritten.
All that works just fine - I'm not asking how to copy files.
But here's an example
Source file is:-
\SomeMachinesomeFolderfile.xyz
Target is:-
P:file.xyz
This might at first look like two separate files but in this case P: is mapped to \SomeMachinesomeFolder so the source and the target are actually the same file and the file copy will obviously fail.
Of course I want it to fail but my problem is that the windows generic error message seen by the user is not very helpful. It says something simple like "... can't be copied because it's busy". If the user isn't very bright he doesn't realize he's selected the same file both as source and target and he doesn't understand why it's busy.
What I want to do is detect in advance that the source and the target are the same file and display a more meaningful message to the user and not even bother trying to copy.
So, is there a way to detect that
\SomeMachinesomeFolderfile.xyz
and
P:file.xyz
are actually the same file?
is there any way that i could link/bind multiple binding source to only one binding source navigator?
