I have an image scanned in 300 dpi. I want to change the DPI of the image to 72 through code. Seems there used to be a function called Image.SetDPI, but I cannot find it anymore. All I can find is Image.SetResolution(xDPI, yDPI), but that actually changes the SIZE of the image, meaning it cuts out a portion of it, without changing the DPI. Anyone know what function will accomplish this in Visual Studio 2008?

I am in the process of creating a relatively simple "yahtzee" game for a final class project. I have a "Roll the dice" button on my form that when clicked chooses 4 random numbers 1-6. Each number is a seperate "dice", each of the 4 pictureBoxes is meant to represent a seperate dice. A series of If then statements is being used for each picture box so that for example The random number is 1, a image of a dice facing the 1 side is displayed.[code]...

I am "weeks new" to visual basic 2008 but I was hoping that someone might tell me how I can open an image in whatever type of "visible" graphics window (always positioned at: x=0 y=0); move to some "definable position" of interest x=(n) y=(n); change the brightness of that "individual pixel" by some "definable means of measure" from its original state; and save the new image as a separate image file?
View 4 RepliesHow do you change the cursor image to an image from the project resources?
The methods I have found either don't work or only change the image within the form, and reverts back to default when the mouse leaves the window.
means the images that will display in the picturebox is based on the value shown on the textbox (ProjID)..
Please see code below..

I hoping to find a current and simple way to do this. I'm using VWD Express 2008 and SQL Express 2008.I'm able to get the client's path to the image file using an asp:FileUpload control on the web form.
How do I upload the client's image file and display it in the web form's image control?How do I save it to the sqlserver? The image table is already set up with a "Image" data type column. Can the image be saved to the database as simply as other data types?

View 3 RepliesI'm getting familiar now with using the Dataset Designer and how it makes for quick and easy updates and query of tables. I use to use the OleDB commands and leave the Connection String as a Global Constant so I can easily change it if the server name changes, or if we have to re-direct the .NET to another instance of the database.
But now that I use the Dataset designer I'm concerned that I maintain flexibility and support in the long run. how the Dataset designer works and where it stores it's connection string info? And how difficult that would be to update. It looks like I modify the App.config file, but I'm unfamiliar with this.
What am I getting myself into? It looks like a standard XML file. Is that it?

View 10 RepliesI have a listview control. it has an imagelist attached to it with two images in it. I have entered items into my listview, and they are using the first image in my imagelist.... GREAT! Now, there is a variable I have that will tell me which index in the listview is currently active, noting to do with what I select that could be at another index it's just what's being processed by the program at the time in some task.
Create a function that will change the images of all my listview items by looping through them. If the index variable is set to 2, I want the 3rd item in my list view set to use the 2nd image in my imagelist. The rest of the items in my listview need to be set to the first image in the imagelist.

If i want to change the image of the button then how to do it?
I've been looking into creating custom controls, and I can't seem to find a good tutorial on how to do so. Everything I've looked at is extremely complex and I simply don't know where/how to start.
To start out with, all I want to do is change the image of the button (normal, hover, and clicked). No extra methods/events/properties/etc. I've made individual images for each situation with Photoshop.
