I am using 2008 Express Edition. I am trying to make a Release build instead of a Debug build.Under Tools->Options, Projects and Solutions->General - I checked Show advanced build configurations. The option to switch configurations does not show up in the IDE.
After this, I went to the Project Properties->Compile and switched the Configuration from Active(Debug) to Release.After building, I looked in my project directory, however only in the Debug sub-directory was the .exe and nothing in the Release sub-directory.I have used Visual C++ Express Edition, where I noticed that if you do not change to Release in the IDE than after changing to Release in properties, resets the project to the last configuration setting which is usually Debug.how to make the Debug/Release box available in the IDE, since Tools/Options does not make it show up?
I just created a simple application. I Builded that using build->build myapp. I got .exe of that application. i runned. all went fine. but when i closed that app, even after closing it is in memory. it is still running. how to deploy it properly?

How can I select that line and change within that line the value of e.g. item 3? (by default it's set to 0 and should be set to a value > 0 when entered by the user.

I just recently started getting an index out of bounds error on one of my arrays at runtime. I was not having this issue previously. It only seems to happen when several items are added to a listbox.
Here is my declaration and code.
Dim ClientActiveMedProbs(frmmain.lstActiveMedProbs.Items.Count) As String
'store all active medical problem information in an array & build a string
For i As Integer = 0 To frmmain.lstActiveMedProbs.Items.Count - 1
ClientActiveMedProbs(i) = frmmain.lstActiveMedProbs.Items.Item(i).ToString
[Code] .....
The actual error message is:
Index was outside the bounds of the array.
I've been trying to reuse my bosses vb.net buildpacket code which he has successful used for Serial programming eg. SerialPort1.Write(buildpacket(useraddress,252,"0006","0") for the function listed below.My challenge.Create equivalent functionality for Socket BeginSend() which requires a byte array.Whether modifying the vb.net below or getting a c# equivalent to work, it has been repeatedly recommended to scrap the string concatenation approach for which I have to use Encoding.BigEndianUnicode.GetBytes() and then getting rid of extra bytes with zero values.
I'm lacking in imaging something different which would work for socket programming directly and allow me to eliminate all the hassles that c# integer conversions into string value that can be encoded trouble free.I would need to call the equivalent of the following that would return a byte array rather than a string with the following arguments
1. Source address (0-255)
2. Destination address (0-255)
3. Function code ("0001" through "0100")

View 2 RepliesI just finished putting the first 6 datagrid controls on my form and i went to go test it and got this build error: Error 4 Value of type 'String' cannot be converted to 'System. Windows.Forms.DataGridViewTextBoxColumn'.C:SoftwareForm1.vb 1425 19..When the line generating the error is this Me.Name = "Form1".where it has the "Form1" portion underlined in blue.This is a weird error because that line was made by the IDE to say the name of the form and has nothing to do with 'System.Windows.Forms.DataGridViewTextBoxColumn'.I tried saving my progress and restarting the IDE with no luck..Now I cannot even access the form in designer mode,One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes.The designer cannot process the code at line 1424: Me.Name = "Form1" The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified.
View 5 RepliesIn my form I have a variable that is of the type Windows.Forms.Form. When my program is enabled/disabled I create a new form instance in there and close it (respectively). Since I don't want the form sitting in memory the whole time my program is open the references to properties of the form are invalid (because the initial declaration is not the form but the type). How can I either negate this or ignore this error?
