View 15 RepliesI'm using this code to search a msacces db and display the data in a listview.The Search is fired after the text_changed event of a textbox. So each character is a search and also each backspace(here's where the real pain is) it will search. When I use backspace its very very slow! When I use 100 or even a 1000 records no problem but this db has 10.000 + records.Whitch event can I use to solve this problem or how can I adjust the code for faster search? ALs o when I test on a windows7 system, dualcore, 2gb memory, when I press a key it will take time before I see the character in the textboxs? Its a new system and only runs this program.I use a texbox to enter for example an artist name and a combobox where the user can choose to search on artis, title, genre etc. [code]

View 3 RepliesI have a few problems i need to solve. Firstly, I am looking for a piece of code i can use to display a picture from a bank of pictures. It will work on the basis of generating a random number and loading a picture that corresponds to that number.
i.e. Dim RandNumber As Integer
Dim RandClass As New Random
RandNumber = RandClass.next(1, 10)
If RandNumber = 1 Then
Picturebox1.image = picture1

Secondly, can I then use subsequent picture boxes to display pictures from the same bank of images, without displaying the same image? Finally, I then need to be able to click the picture or a button beneath the picture to select it as an answer to a question and then the whole process starts again.

i have to create a mortgage calculator (I know we have killed this mortgage calculator). Has to display an amortization table to display the list after doing the calculation. Here is the actual assignment:
Write the program in VB.Net (not Web based) and have it accept user input of the amount, term and interest rate. Display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term of the loan. The list will be longer than the screen, so use loops to display a partial list, hesitate, and then display more of the list. Insert comments to document the program.
I have created 4 buttons. Calculate, Clear, List, and Exit. The buttons all work, but the list does not. Not sure what i am doing wrong.

I am trying to get a routine to work in vb.net which will cycle thru a datatable which contains the path to various images and display each one for a specified time. I am starting the routine with a timer control and the images are then displayed indefinetly.The problem is they don't display and then when the routine ends it shows the last picture in the pictue box. When I trace it, it is correctly getting the path of each image but the line "Me.picbox.Image = Image.FromFile(path)" doesn't load the picture to the display. IF I let the routine cycle once so that it ends, the picture box contains the last image.Is there something I have to do to force the refresh of the display? [code]
