I want to populate a listview and leave selected records that are true
I have a DB record which is ID int, desc varchar, selected boolean.
I have tried the code below
LVProducts is a Listview and DS is a dataset
CODE:
I have a vb-2008 program that contains a (listview) control.
View = details
AllowColumnReorder = true
Lets say the table has 3 columns (a,b,c) and 1 row of data.
a b c
1 2 3
I want the user to be able to re-arrange the columns (by dragging the column headers) before printing the contents of the table.
c a b
3 1 2
Statements like:
.. ListViewX.Columns(2).Text
.. ListViewX.Columns.Item(2).Text
.. ListViewX.Items(0).SubItems(2).ToString
Give the column-name (c) and cell-contents (3) of the origional table .. not the (3rd) column (b) of the re-arranged table.
How can i get the column-name and cell-contents of the (3rd) column of the re-arranged table?

I am writing a program where the user has to log in before the program loads. Right now I have all the users and passwords hard coded into the program. Recently I have written a Oracle function that the username and password is sent to the DB and a yes or no is sent back after comparing the passwords. I am getting the correct response back and it will display in a label (I tried it to make sure the response is correct). The problem I am having is that the program after receiving the response doesn't recognize the response so I always get an incorrect password error.
Below is my code:
empName = tbxUser.Text
passWord = tbxPassword.Text
dbConn.ConnectionString =
"Data Source=!!!!; User Id=!!!!; Password=!!!!"

View 4 RepliesI have my program working that loads flash movies and games for my son to play offline. Some of the games have http links in them. Is there any way that still allows playing the game without launching a webpage request? I have no code for this part of the program because I don't know where to look. I think I am just looking on how to block requests for launching anything outside of the program, or catching the request while my program is running, but not quite sure what to do.
View 5 RepliesI am trying to write a program which loads a tiff image on picturebox. Then the user clicks somewhere on loaded image to set the starting x,y coordinates and clicks again to set the ending x,y point. Then clicks the run button and the starting and ending x,y points are written on label.
Just to test the program a loaded a tiff image that has a dimension of 75x75 pixels. When I click upperleft and downright corners of the image, the program outputs the coordinates as starting x,y as (103,89) and ending points as (170,157). The program outputs wrong coordinates becayse the image has 75 rows and 75 colums only. To me, it should have outputted starting point as (0,0) and ending points as (75,75).

Everything works on MY comp, but when i go to my lil sister comp and load the .exe file there, everything works too EXCEPT the image....the error is something along the line " C:documentspictures ame.jpg" not found.

And I dont know how to create and work with .dll file or whatever file is more convience.
