View 4 RepliesI have already incorporated DirectX into a program and set the owner to a picturebox which so far works great, but all it does is set the place/dimensions of the directx window to the picturebox... it doesn't actually USE the picturebox for the video so if i pause the video or set a timeframe I can't use the picturebox frame/image to pull information from. So what I want to do is when i pause the video at a certain frame I want to be able to actually take a snapshot and populate the picturebox with that image and then be able to save/manipulate it like a normal picture. I have read some examples and coding on screen snapshots using DirectX.3D, but not audiovideo. Not sure if its the same or what. I know normally you would start out with CODE, but in this case I have NO IDEA exactly where or how to start it.. I tried Bitmap options with the screen area/location, etc... but was getting errors and exceptions..
View 2 RepliesI need to capture image from WebCam in my .NET application which should work on both Win XP & Vista. While creating this thread, the forums suggested me 3 links that were helpful. I though I got the answer from one of them, but it worked spcifically on Win XP, not Vista.
I jus tneed to capture an image from the WebCam, rest all processing of the would be handled by my .NET code.
I'm trying to take a snapshot of a website and show the snap shot in my picturebox.
the only thing on my form would be the picture box and a button to take a snapshot.
I would like to be able to take a snapshot of an whole RTF document displayed on screen (and also whats not yet displayed below screen) and save it as a JPEG image, but I cannot work out code to do this in VB.NET.I can do it all manually by displaying the document on screen, highlighting all text displayed and copying it to the clipboard. Then I can paste it into 'Paint' and save it as a JPEG. But I would like to be able to do this programatically inside my program.
View 5 RepliesI have been using the VB2008 express edition following Bob Tabors's 18 course lesson in VB 'snapshot 5'. I was starting lesson 14 on the RSS reader. This lesson adds the .mdf for the first tome. The .mdf file was unable to be opened due to some message about code 603?. The final requst is that the database be recreated. What would you suggest. I was not expected to run into this problem so quickly in the learning process. so be it
View 3 RepliesI have a third party GIS tool that I'm using to view maps with. Occasionally we have to take a snapshot of a portion of the map and dump it to a bitmap. The third party tool has a function that will give me the upper left and lower right coordinates of the area selected on the map. These coordinates come out as system.drawing.point objects.
The two point objects are then used to generate a new system.drawing.size object that will give the height and width of the area selected. The height and width values are passed to the constructor for the system.drawing.bitmap.All this works fine most of the time. Sometimes, however, when the user selects a particularly large area, the bitmap constructor bombs with a 'parameter is not valid' error. There isn't any documentation on this error, but I'm assuming it means the height and width are too big.
So what I'm wondering is... is there some way to check my height and width values prior to creating the bitmap and make sure they are in acceptable bounds?
I am trying to take a snapshot, or a copy of a control, for a bitmap. I'm wanting to do this to a listbox, but part of the listbox may be hidden.On the mouse_down event I need to get the snapshot of the whole listbox (even though parts may be hidden behind other controls, I need the whole listbox) and draw it to the screen in the same location as the original listbox (but the hidden parts still stay hidden behind the other controls on the bitmap).
On the mouse_move event I need to move the snapshot up/down based on mouse movement. This also moves the listbox up/down and this code is done. I will just move the snapshot of the listbox the same way as the original listbox.On the mouse_up event, I will dispose the bitmap and display the original listbox again.
I am doing this because moving a listbox up/down is really messy. It's a custom drawn listbox and looks horrible moving, so I figured if I could snapshot it, move the bitmap while visible, and listbox behind the scenes, it will flow smoothly and no one would notice I am scrolling a bitmap instead.
Double buffering the form and listbox didn't help . I've done some graphics.drawstring before, but not much on other graphics.
I need to take a snapshot of a form which is not necessarily visible on the screen. I need to save that into a Bitmap object. I cannot use Graphics.CopyFromScreen() because if there was anything obstructing the form, it will appear in the snapshot taken.
View 6 Repliesi have seen google chrome, whenever you open a new tab, it will show you the last 8 pages that you have visited. I want to do a similar thing, except i have a vb.net code behind the .aspx file, which shall give me a list of URL's called form the database. When the page is loaded the URL's are displayed on it. what i need my code to do is to pick up these URL's, on the background open a web browser, take a snapshot of it and save it, and display it on the screen. dont recommend IFrames cause I need a snapshot and not an actual running site in the small snapshot.

so i have a quite huge program. but lets say i have one label. and i want to save that. i have the code and everything for saving the text of the label. now i want to assign ctrl+s to automatically save the labels text once pressed instead of going through a menu to choose save.this is like a regular texteditor where u press ctrl+s and it saves.
ive used this
If (e.KeyCode = e.Control & Keys.S) Then
MessageBox.Show("Ctrl+S pressed")
End If
and

but it doesn't do anything once pressed.im also using the keydown declaration for the form.
I have researched the net, youtube, and the msdn DB, and still can not find the working answer I am looking for. I would like someone to show me how you would save the contents of "Listbox1" to a .txt file using the "Save As" Option. I know how to hardcode a savepoint in, but since there will be multiple users I would like the option to be up to the end-user.
View 4 RepliesI want to make a save button to save to a new text file with the data in the text box if modified. Currently the program just opens Data.txt and displays a sentence in the text box.

My question is simple (the answer may not be...), What I am looking for is a way to save a file as an encrypted file (so know one can open it except in visual basic or a way to save it with a unique ending that only visual basic will recognize. I will also need to know of a way to open or load the file to.
This is going to be used in a game I am working on (and yes...I know visual basic isn't really meant for games, but it is coming together pretty well). I was originally going to have it save as a text file, but then everyone could open, read it and even change there stats. That is what this file will contain, the stats for their character, and when they load it, it will place the values into the correct spot.
I am a partial beginner or intermediate coder, I can understand code, I just don't know all there is, like saving and loading, and this is probably a little harder.
I am working on a form that save contents of a TextBox as a txt file, but I want to make my own file type, with the extension .rcp. How do I get my save Button to save as .rcp by default? [code]

In a word processor of mine, I made a save and open feature, but, I'd like to improve my save feature, so that, when the user tries to save, it doesn't make the user choose the location every single time. So I pretty much want my save to do the same thing as MS Word when you try to save.

View 2 RepliesI have been developing a database management program which is quite simple so far, with navigational controls, ability to delete record, datagrid, etc.
It uses databound textboxes, but when I modify the content of them it does not update the database. Same applies when I add a new record and fill in the textboxes. What do I need to do?
