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'm looking to use a timer to change an image for a set number of times & then exit. Am trying the code below but although the TextBox check works the Image skips directly to the second from last & goes no further.
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 to change the image when I mouseover on the image and when I not mouseover the image, returns to the image where it was. Is it possible to have them on vb.net??
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?
The issue is how do I best capture the invoice number of an tiff image?
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.
This is probably an easy question: I need to change my version number from 5.4 to 5.5. This is not the assembly version, but the version (I think) of my executable.
I have written a code that when the click the calculation the button a inputbox pop up and you enter in the income and then you enter in the expense. [code]...
Currently just started working with VS2008 I have a SQL script that is returning a number looking time in one of my columns (50625) which is 5:06:25 What I would like some help with is creating a function that would take this value and change it to a real time at some point I will need to do further calculation on these times so I need to be able to add or subtract these results.[code]...
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.
My code gets a list of words from a txt file and chooses the words randomly. However, the same word can appear more than once and i need to know how to stop this from happeningHere is the code:
Dim aryName As String() = Nothing aryName = File.ReadAllLines(Application.StartupPath & "Randomfnames.txt") Dim randomWords As New List(Of String)
I have this recently converted application from vb6 to vb.net 2008. One of the errors stated is:'Point' is not a member of 'System. Windows. Forms. PictureBox'.I have searched and not found an alternative to this.Also, it says ReDim cannot change the number of dimensions in an array.
I would like to be able to create a function where I can change the probability of a number being outputtedI am creating (Well have created) a slot machine game but the outputs are completely random and I would like to change the odds. Is this possible and if so could someone show me or direct me in what I should do to create this function.
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]
On the (1) line, I just want to check to binding from database successful. It well done.Then I try display images on picture image when user move on datagridview but it doesn't change. It's only show the first image which it read from database.How can I change these images when user move on datagridview?
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.
