TV Tuner USB Stick - AxMSVidCtlLib ?
May 11, 2011I bought myself a TV tuner USB stick, and the supplied software does not do what I want. I looked around for some software examples, but everything I've seen uses DirectShow which was apparently part of DirectX-9, but does not seem to be in DirectX-10. I've found AxMSVidCtlLib, but have not been able to work out how to use it.
View 2 RepliesVS 2010 - Stick An App To The Desktop Background?
Jan 7, 2011I would like to have my application basically appear as if it was part of the desktop background, I've removed the form border etc and made the background colour of the form the same as our standard company background so it all blends in nicely. I have also made it so the app does not appear in the toolbar and it is set to launch on startup so it appears as soon as the user logs in - so all works fine and looks fine because any new apps that the user opens will open on top of my app. The only problem is that if they press the Show Desktop button (or use Windows Key + D) to minimize all apps, mine gets minimized as well and disappears. Its easy enough to get the user to make it appear again as it has a system tray icon that they can interact with, but it would be better if it just didn't vanish when they did this.Now I know the best thing for this on Windows 7 would be a Gadget but the problem is that Gadget's annoyingly have to be HTML/javascript and a) I'm not great with web coding and b) I don't think it is even possible to do what my app does from a HTML/javascript page... oh and c) I can't find any way to deploy gadgets in a business network (there is no way we are installing it manually on all 300 of our PCs), so the gadget idea is not looking very promising.I'm wondering if there is some window message I can capture and ignore in the WndProc event handler

View 2 RepliesUSB Flash Memory Stick Auto Detection?
Feb 14, 2010My whole project consists of:
1. an electronic product
2. a memory stick (USB mass storage device) and
3. CD thast includes the Windows user interface program
The electronic product acts as a host controller that write data to a file (.wcs), which is in the memory stick whenever the user plug it to the USB connector. After this the user disconnect the memory stick from the electronic product and plug it to a PC that run the user interface program. Untill now the user searches for the .wcs file manually using an OpenFileDialog.
My question is:Is it possible for the program to automatic detect almost plaged or new plaged USB flash memory sticks in order to load open the needed .wcs file? If this is possible then how can I do it?
VS 2010 - External File Paths (USB Stick)
Aug 27, 2011I am trying to write a simple standalone windows forms project that basically contains various buttons which run external application setup files. The problem is I want to be able to run it from a USB stick. I have created a folder inside the project with all the files I need to call in it. I am using Process.start but the paths are obviously going to be wrong when the project is running from the stick as the drive letter may be different each time. How do I over come this.

View 2 RepliesRichTextbox - How To Mark Cursor To Stick In Character Position
Mar 7, 2011I am using a WPF richtextbox to create a syntax highlighter for code provided in a textbox. I want to have it automatically adjust the rich textbox as I am typing, using a thread timer I reset the contents of the rich textbox. I am trying to keep the cursor where it is suppose to be. I don't loose any text characters during the parse (except line breaks).
I don't know how to keep the caret position where the user has left it in the text. It defaults to the end of the document. I attempt to store the current caret position in the text and then set it to the document after I make my changes, however the error I receive is "Cannot set CaretPosition to be outside of RichTextBox." So I set the caret position to the bottom of the document.

View 4 RepliesMake Object Follow Mouse On MouseDown And 'Stick' On MouseUp
Apr 14, 2011I'm working with a project that is WPF and VB.net. I want to visually simulate "dragging" an object (though I do not want to use standard drag and drop for reason of purpose).Basically, I have a label object that, on its MouseDown event, I want it to follow the mouse cursor inside a 640x480 solid-size grid (but not outside of it!). Mind you, this grid is centered inside a full-screen window. Again, the object should not follow the mouse outside of the grid (I'm guessing a "ClipToBounds = True" here)Then, on the label's MouseUp event, I want it to either stay in its current position or return to its original position, as determined by the value of a boolean variable set by another object's MouseEnter property.Note, if it would be easier to work with, I can change the grid to a canvas in a cinch. I'm guessing that would be desirable.
How do I make the object (label) follow the mouse cursor inside the grid/canvas, but not outside of it? This needs to happen on the MouseDown event of the label.How do I make the object "stick" in its current position? (From this, I can probably figure out how to make it return to its original position on my own.

View 3 RepliesVS 2008 - VB BITBLT Equivlant - Build Image By Opening Files With Image Data
Nov 2, 2010In VB6 you could BITBLT things around before refreshing the screen. In .NET, I'm aware of DrawImage, but that can only be done on a paint event rather than before anything gets painted. The issue I have is, I need to open several files with image data in them and then build a bigger image with those smaller images. Before I could open them, BITBLT them to a Buffer. As far as I can tell .NET offers no way to do this as the only function I've been able to find (DrawImage) only works within the paint event. Is there still a way to do this in VS08 or no?
View 6 RepliesVS 2008 - Image Transparency - Loading A Bunch Of Pictures On Top Of One Image
Oct 14, 2009Ive been programming in VB6 for years, i figured its time for an upgrade. Here's what im doing, and what the problem is:
Im loading a bunch of pictures on top of one image. They are all PNG files, and some of the images have transparent edges, and some semi-transparency within the image itself.
So basically, i need to be able to load these images on top of the other images, and still maintain the transparency.
Is this possible in VB08? This is one of the main reasons i moved to 08 from vb6, more things possible including multithreading.

Loads Up 4 Images If Usb Stick Is Checked And A Different 4 If Memory Card Is Checked?
Feb 20, 2010project im working on for my course,the idea is a photo printing machine that loads up 4 images if usb stick is checked and a different 4 if memory card is checked. and then whatever image is selected appears in the big picturebox on the left [URL] i have 2 print size options set as radiobuttons, radiobutton 1 = 6x4, which costs 25cent per photo, radiobutton 2 = 8x10, and is 50cent per photo.i also have a textbox which will display the number of copies to be printed So here's my dilemma, when the print button is selected alongside one of the radiobuttons i want it to display a message saying something like this "you have selected (whatever the amount of copies)of this photo sized 6x4, or 8x10 depending on which radiobutton is selected, and i want it to display the total cost which is the number of copies multiplied by the rate for the print size selected, then an option saying "Do you wish to proceed" Yes or No.
I did something similar to this in class earlier in the year but cant remember it, it was an airline booking program with 3 types of payment cash, visa or mastercard,upon booking a message popped up saying there is a certain percentage discount for using visa or mastercard
