Does An Image Hash Number Change
Mar 31, 2010
I saved an images hash number to a database so that when my application pulls in images, I can compare this hash number to the hash numbers of the images comming in. The purpose is that if one of the images comming in has the same hash number, I can flag it. It seems that the saved hash number for an image is not the same for the exactly the same image when it has come in. Is this because the hash number for an image can change depending on the pc where its being created?

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?

How 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.

I 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.

I just want to know if the following behavior is by design. I start Visual Studio and open my VB project and rebuild it. The assembly version is set to 1.0.*. I get a version number of 1.0.2839.26817. Now as long as I keep visual studio open every time I rebuild, I get the same build and revision number. I have to close and reopen visual studio to get the revision number to change. Again I just want to know if this is by design since everything I have read says that the revision number is either supposed to be random or the number of seconds since midnight. Is there a way around this?

I have a VB application in visual studio 2005 that scans invoices, creates .tiff's utilizing a standard image scanner.
I've tried the following...I thought I could save the image to text in an array and find the 6 digit number. Then, I tried to save the image to xml trying the same principal but I get a general error A generic error occurred in GDI+.

In the process of creating an Icon object, I need to reduce the numbers of colors in an image from thousands down to 256 or less. I do this by "chromatizing" the RGB values - counting the colors - then re-iterating the process with heavier "chromatization" until the number of colors is reduced to my requirement.
I searched these forums and google on this subject to find out more - but I found that I alone call this process "chromatization" it seems. So I was hoping someone could help me out with the correct terminology.
Specifically, I want to use the correct terminology on my UI buttons (at present I have a button labeled [Chromatize] . .) and I am curious as to whether it would be good practice to "chromatize" the Green most heavily, the Red more moderately, and the Blue least . . . or just "chromatize" them all equally which is what I have been doing

I have the following code. When I use:
For i = 3 To MaxColumnDataGridView
DataGridView.Columns(i).DefaultCellStyle.NullValue = 0
DataGridView.Columns(i).DefaultCellStyle.Format = "N5"
Next
The columns format can't be changed. I cannot change the number format whatever I do.

I'm doing a school project with arrays and I want it so that I input a part number and it outputs a image, price, and name for the part. I need to accomplish this using the array. We've only ever done arrays where you input a part number and one thing comes back out, not multiple.

I need to be able to count the number of pictureboxes whose image is not "nothing". At first, this seems really simple (and it probably is) but I'm unable to see a way to access the array I created. (This is a workaround to the .net framework's lack of support for control arrays.)Here's the code as it exists now. Please look at it and give me a pointer in the right direction.[code]

I am at a bit of a loss at the moment. What I am basically writing is the password elements of a membership system. What I do is generate a random salt value, take the registered password, combine the two and then pass the new string through a function which will generate a SHAManaged 512 hash.
I then convert the hash and salt string into Byte arrays and store these in my database.The problem comes when I then compare a login attempt against the original value I am being supplied with a completely different hash for the password being presented by the user, even though it should be exactly the same.
Here is my code when someone registers their new account:

If there is a formula to change a latitude and longitude into a single number? I plan to use this for a database table in software that provides routing for deliveries. The table row would have that number as well as the postal address. The database table would be sorted in ascending numeric order so the software can figure out which address the truck would need to go to first, second etc.
For example I would use the following numbers for the latitude and longitude:
Lat = 40.71412890
Long = -73.96140740
Additional Information: I'm developing an Android app using Basic4Android. Basic4Android uses a VB or VB.Net syntax with SQLite as the database. Part of this app will have route planning. I want to use this number as the first column in an SQLite table and the other columns will be for the address. If I do a query within the app that sorts the rows in numerical ascending order, I will be able to figure out which postal address are closest to each other so it will take less time for me to go from house to house.
For example, if the numbers were:
194580, 199300, 178221
I can go to postal address 178221 then to 194580 and finally to 199300 and I won't need to take the long way around town to do my deliveries after they were sorted. As an alternative, I would be happy if there was an easy way to call a web service that returns maybe a json response that has the single number if I send a postal address to the web site. Basic4Android does have http services that can send requests to a web site.
