I've got a DataGridView that has a DataTable as it's Datasource. Whenever I sort a column and then edit a cell, after editing the column, the column autosorts so the recently edited cell is no longer in the viewable area. Is there any way to prevent this auto sort from happening and only sort when I click on the columns?
View 2 RepliesI have implemented couple of websites) drag and drop functionality between two Datagridviews (i.e to be able to add/remove columns on the fly). After much playing, I have managed to make this work, however it now presents a new issue - I cannot resize the columns.Below is the code for this, but I can't see how I would need to change to accomodate the resize (the drag and drop effects dont have it as an option, so I assume I need to stop the dodragdrop when the resize is taking place, but I'm not sure how to do this.

View 1 RepliesI am going crazy trying to figure this one out. I have been told many times that you can get the data of a column in a listview in this manner: YourListView.SelectedItems(0).SubItems(1).text This does not work. I have a ListView called EmployeeListView that is correctly populated by my database. There are three columns: (0) is First name, (1) is Last name and (2) is Employee ID. I can see the information in the ListView when I run the program. What I need to do is to pull out the Employee ID and put that into a variable called EmpID.

View 1 RepliesI often face the following problem : when I have a form with lots of controls on it (100 , 200 etc) and I change the name of a control , the IDE goes slow for a few seconds . This is very annoying when I have to change the name to a lot of controls . I believe this is happening because the IDE checks the forms , the code etc to see if there any problem after (re)naming the controls . Of course this is welcome because it prevents a lot of problems , but at the same time it creates some serious problems as well . Thus , I wonder , is there any way I could prevent the IDE from checking all those things in order not to reduce it's speed ? Of course I am talking temporarily . I believe that what I gain by letting it check after every name-changing , I also gain it if I only let it check once (at the end of the name-changing process) .

I have 1 listbox and 2 buttons and some images in the form. So what is the best way to do
View 15 RepliesCurrently, my application is comprised of:a Main Form On this Form, lies an array of User controls, (pardon my terminology, i believe the more proper VB.Net term is Collection of controls). Within these controls are pictureboxes that have distinct graphics drawn on them. When I run this program, no graphics are drawn in the pictureboxes or it appears the graphics are overwritten. Also, it seems that the Form resizes uncontrollably varying in size on the screen and hits an infinite loop. I use the Form_Resize function for updating the size of the form. What could be causing this problem. What is the Paint method used for?Currently, to draw graphics on the Pictureboxes i am using the graphics object. I have two pictureboxes within the usercontrol for toggling back and forth for a more fluid refresh upon property updates.
From my reading, vb.net does not allow the ability to create an array of controls on a form, so I attempted to create an array of controls dynamically to try and stay as close to my vb6 application as possible because my knowledge is limited. This works, from what i can tell I know that in the Upgrade wizard the VB6.Compatiblity reference was used to try and mimic an array of controls, but I wanted to steer away from that and program strictly using VB.Net commands.
I have a form that is hard coded to be 1182 x 780.

I have a form that sits on the user's desktop. It's only purpose is to display specific information about the computer. The layout is basically setup like this:
[Code]...
I want to be able to give the user the option to display whatever data they choose. In doing so, I'd like the form to resize itself based on the how many labels are in the form and for the labels to align vertically.
Can anyone point me in the right direction? For the form, I was thinking I could get the location of the last label and offset it's size by the location, or something similar.
developed my app on a Vista laptop and deployed it on an XP desktop. When deployed the Form and even some controls are resized so text and portions of controls are not visible.Next I moved the project files and VB to the XP desktop and published the application on that machine. Same result, in fact the sizes were changed within the properties of the forms and controls within the project files
