I'm loading files into a listview (1), which works fine. Now I'm trying to load records into another listview (2) according the Listview1.SubItems(2)-record.I tried several times, but without succes. One of the commands;
Dim cmd_data As New SqlCeCommand("SELECT Field1, Field2, Field3, Field4, Field5, Field6 FROM Tablename WHERE Field2 = Name_Form.Listview1.SelectedItems(0).Subitems(1).text", connStr)
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?
Do I really have to go through all this just to find out what item has been selected in a ListView?

I've been looking through MSDN, but I can't seem to find anything at the moment.
I start my program with a splashscreen and as soon as the mainform is loaded, databases are loaded and data is crunched it shows the form with everything on it. All very nice. But now comes the trick. The form has a strip of 5 tabs on it. The active tab is shown and directly accesible but as soon as i click on the other tabs it needs time to draw everything and calculate its content. And when i have clicked through all of them everything is finally up to speed. How can i speed things up in such away that all this predrawing etc is done in the background just as i got it to work with my mainwindow and its first tab?
I have this in the load sub:
For i = 0 To TabControl1.TabCount - 1
TabControl1.TabPages.Item(i).Invalidate()
Next
But some how this does not do the trick.

View 1 RepliesMy question maybe not be very clear, but I just want to know how this process is called or references needed to create something similar, so I can investigate on my own ( but if you have code is welcome.Basically I have 2 desktop programs ( A and B). For A, I do not have the source code, for B I do.What I need is to create some service/program that after a screen pops up from program A, automatically runs B. IN other words, capture the moment a specific screen is shown in A and execute B.
My real life scenario is that I have a very basic POS where I can't collect customer demographics ( zip code, etc), so I created a second application to capture that but my cashiers are always forgetting to run the program and I need to find a way to run it after a screen is shown ( let's say the "Change Due" in the POS, so they don't forget to run it.
I have updated a VB 2008 Winform program and published it on a shared folder. The customer can no longer use it because, at launch time, it claimed for SQLServer.Diagnostic.STrace v 10.0.0.0, what it did not before. The only thing I can think at is that I have also recently installed VS 2010 on my PC. Does it change the way VS 2008 work ? How can I solve this issue on the customer PC ?
View 2 RepliesI 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 am rewriting an old app that uses Linq. One part intrigued me...The code get the ID of a row from a datagridview.Then the code executes a LINQ that in the where-part make a selection based on the ID (which is the PK) to return a single object using .Take(1).SingleOrDefault Then this object is added to the dbcontext.Employees.DeleteOnSubmit() method and finally the Submitchanges is executed...I added a watch to the Log property of the datacontext, and lo and behold, when the delete query is executed, it uses ALL properties of the object in its where query. It should use the EmployeeID only since its the PK.
My question is, is it impossible using LINQ to execute a simple "delete from employees where employeeID = 1" That is basically what the above LINQ code does. But I dont want to to excute a select statement first, and I dont want it to delete by all columns, only by the id column, which an indexed PK.Any LINQ gurus wanna share some insight on this?
