View 10 RepliesI have written an vb.net application, named vbapp.exe. And I would like to use vbapp.exe to shell an external .exe file and this external .exe will create a file in the folder in which the external .exe file is located.However, the external .exe file will not recognize its own folder, on the contrary, it will think that its own folder is where the vb application, vbapp.exe, is located.

And move them outside of the web.config or something simlar? I find these nodes at an extreme amount of noise to a web.config when they're relatively static. Normally my approach would be to config source something like this but since it falls under the root node I'm not sure of it's possible with these nodes.

View 2 RepliesBy the EnumChildWindows API I can know the Hwnd of the ListBox control of an external application. By the Hwnd I can too to select "generically" the control by a PostMessage API, also if the application is not the foreground window.
Now the question is: is there way, in your opinion, to select a specific item of this external list box, also when the application is not the foreground window?
I'm trying to build a project where I have a set of products in a listbox. When you select an item in the listbox, a picturebox shows the preview of that certain product.I practically finished the entire project as well as the picture part; however, I realized that the way I set up the coding, I used image locations from my hard drive meaning that someone can't view them on another computer.This is a portion of my coding:

I have been programming for alot of time. Generally i program in some languages like PHP, ASP.net, Java, JavaScript and others. In all languages i have to use alot of if else statments .

I was so happy when I discovered IsLittleEndian field in BitConverter. I thought of course it should be there and I should be able to specify whatever endian I like. Well, my happiness didn't last long. Spent some time till found out that there is no way to set the field.The field is readonly, and it is only set to true in static constructor:

My question is: how come there is very useful piece of code that is already implemented and sitting there in the FCL, but there is no way to use it (unless you start messing with reflection of course)? Is it just because some developers didn't meet the deadline and left the job half-done? Even if so, why the code is not available, but the field is?I hope there is a good reason for this.
I want to make myself clear. I don't need a solution on how to handle big-endian values. I do have a solution. The solution is actually shown in my question.
I have a DataGridView and one column has DataGridViewCheckBoxColumn type .The datagrid loads from selected items of a listbox.I need to hide Check box cell in this grid according to the item.

View 3 RepliesThis LINQ to SQL query From g In Db.Context.Current.Groups Select g.GroupID

I can't remember very well the instances where my selected items has disappeared as if I did a "Reset ToolBox", the last time I remember was when I installed the Service Pack early this year. But last year I think it has been reset frequently and I find it bothersome to reselect all those items again and again.Is there any configuration that I could set so that my selected items are safeguarded, that is they won't be removed no matter what?
View 4 Replieswhat exactly the difference between using cases and if statements are.
View 4 RepliesI am having trouble figuring out what I need to do in order to get the program to drop into the different cases. I am suppose to be doing a case block for this assignment.

Im trying to to detect what is in the string and so something for each different result but im not sure howto, here was my first idea but it obviously doesnt work as you cant use contains that way:
Select Case omg.Contains
Case "1"
MsgBox("1")
Case "2"
MsgBox("2")
End Select
I am working with cases, I'm only learning it so far, but just can't get a drop down menu to work that would change the background of a Textbox.
Private Sub cbColours_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cbColours.SelectedIndexChanged
Select Case colours
Case Is = "Red"
txtSpace.BackColor = Color.Red
[Code] .....
It isn't doing anything at all...
In the dropdown menu, it has
Red, Blue and Green one per line
When the value (e.g. Green) is clicked, it will then change the Textbox to the colour selected.
Formatting the input text to upper and lower cases e.g Start with a capital.

View 5 RepliesWhat purpose do protected or private (non-static) events in .NET really serve?It seems like any private or protected event is more easily handled via a virtual method. I can (somewhat) see the need for this in static events, but not for normal events. Have you had a use case before that clearly demonstrates a need or advantage for a non-static protected or private event?

I have 2 group box components and both are same size,font,location and visible is false. When i click button2, the groupbox1 won't appear(the group box2 is on bottom n group box1 is on top).
Example:
button1
groupbox1.visible=false
groupbox2.visible=true
button2
groupbox1.visible=true
groupbox2.visible=false
Because i want to show the different,so the location have a little different(actually both are same location). I think my code is no problem. The problem i guess is both component cannot locate at same location?
we have a user that my program works fine for.. and another that it just crashes for.. they get this error
"You cannot start application <App_Name> from this location because it is already installed from a different location."
then they run it up again and it comes up.. and then just closes..in reading some stuff online it says its a framework 2.0 sp 1 issue ?these pc's have 3.5, but my program uses all 2.0 stuff..so is this a 2.0 sp level issue ? or should I make my programs start to use framework 3.0 instead ?
I was using this old method of creating a bunch of rectangles when I need to get the location of a certain point within a grid so I could draw images on the grid. The thing is, I don't want to use rectangles, I want to be able to just round the location as if I were using rectangles. I need it to be able to round the point (66,70) to (50,50) so if you can imagine a grid and the mouse position being within that square in the grid, I need to get the location of the upper left corner of that square.
