This is for my really advanced game maker. Which is really working well. But when I went to remake the game player and speed it up, I quit painting the map on the form and the char. So my idea now is the make a picturebox on the form contain the map image and then make another picturebox on top of that one. Now the first pictreubox contrains controls the user created, very useful thats why I switched to a picturebox. And the second one contains the char,anyway, The one that contains the char needs to be able to show the controls behind it, or my game maker wont work. The char image its self is transparent but I need to make that picturebox show all the controls behind it so that if that picturebox moves onto a user control they can still see it beneath the char.

I have designed this app with 5 pictureboxes. Each picturebox shows an image of a variation of a particular chord. Now, when a user types in (let's say) Cmajor (and it auto completes) how do I get the 5 pictureboxes to show the 5 different Voicing (Variations) of the Cmajor Chord?
View 15 RepliesI am trying to get a access picture attachment to show in an vb.net picture box. At start up, I add an attachment field to the database, and add pictures to the database in jpg form.

However, when I go to run the program the picture box remains empty.

1) Add a new record - I can currently add records text to access database, but not images.
2) Get the ID [URL]I'm not sure how to integrate this code into my code. I am stuck here.
3) Save the image in the filesystem using the ID as a filename - I can save the upload an image and save the image to a directory on my computer, but I am unable to name the image that of the ID of the access database.
4) Update the database to put the filename in the record you just created. - I am unable to do this as well (obviously).

I have a form containing a listbox showing a list of image names. It's bound to the database table. When an image name is clicked it shows the image and imagename in a picturebox and textbox respectively. When no image is selected in the listbox, a new record can be inserted by browsing a new image in the picturebox by an openfiledialog, writing the imagename in the textbox and pressing the OK button. When an image is already selected, the record can be updated by pressing the same OK button. The data is saved into MSSQL Server 2005. Corresponding table fields are Keycode int autono, logoname nvarchar(50), logo image.Now the problem, when I insert a new data with an image everything goes fine but whenever I try to update an existing data with an image it throws an exception- 'A generic error occurred in GDI+.' at the following line- 'pic.Image.Save(ms, pic.Image.RawFormat)'. Surprisingly when I update an existing data without any image in the picturebox no exception is generated. I have crossed checked it and seems that the problem is just at one point- 'Updating the image from the picturebox'. My code to insert/update the data by OK button and to populate it by listbox doubleclick follows:
Code:

Private arrImage() As Byte

is that instead of receiving data from one row and assigning it to the same array Im receiving data from multiple rows, but the information is the same because its from the same one column from the database. The error I keep getting is 'index out of bounds of array'

What it does is it loops through once and retrieves the first value from the db then it throw the exception when it goes to retrieve the second value.

I'm using VS 2010 and MySQL 5.5. I've got a data grid view displaying the results of queries entered by the user, shown below. It works; the trouble is that if there's an image in the results, you'll only see a cell-sized very long thin strip of it.
So I want to a) resize any images to a reasonable thumbnail height (say, 100 pixels, naturally maintaining aspect ratio) when displaying them, and b) resize the row to fit them.[code]...
I am trying to select multiples rows from a database table and insert the text into several "label" controls. For example, if the database search returns 5 results. then insert the first row's text into label 1, the second row's text into label 2, and so on. The number of rows will be variable. I was thinking of a while statement. I am having a problem understanding how to even seperate multiple rows from a query in VB. Would using an array for the query results be the right way to go? row one would be row(0), row two's text would be row(1), etc.
