View 3 RepliesI'm in high doubt of this actually exsisting but still want to check, is there a way so that whether the VB form has focus or not it can still read the keys being typed? I am using winamp and i type something and the form picks it up, so when i type something like ctrl+"exit" the application closes. the thread should be running as the form is Always on top, however for obvious reasons the form does not have focus, so something like keyPressEventArgs won't have an effect, is there any way that you can catch the keys in a global perspective.

View 1 RepliesI have a solution with 5 visual basic projects in it. Each project has an identical module with a few functions and constants - like handling our RS232 data, outputting events to log files, etc, etc..
If I want to change any of this common code, then I have to manually go through and change in each project. Is there a way to have a single module or class that's shared throughout the projects in the entire solution? I've considered creating and referencing a class library, but I'm likely to be making several little tweaks and changes to this "global code" and that method sounds like it could be just as awkward. Can I not just have a module that's visible to all projects, and compiled into each one seperately when the solution is built?

View 3 RepliesI have a main form with 2 splitcontainers. On the left is a richtextbox showing the clients details and how many active tickets they have open and cmd buttons which opens different uc's within the container on the right.What I am attempting to do is when a client raises a new ticket, that the global variable holding the ticket count number updates via a procedure and updates the richtextbox on the main form.The line of code that runs within the UC is:
formMain.SplitContainer3.Panel2.textUserDetails.Text = FullNameSQLString & vbCrLf & UserDepartmentSQLString & vbCrLf & vbCrLf & "You have submitted " & Global_FCRCount & " ticket today."
The part I have highlighted errors with the following reason: 'textUserDetails'is not a member of 'System.Windows.Forms.SplitterPanel'.I have checked and double checked the form names etc and textUserDetails definately exists within formMain.SplitContainer3.Panel2.

View 2 RepliesIn my current project everyone names variables and methods after what they are and what they do. This is good for quickly understanding the code, but with a lot of long varible names comes some headaches, such as when copying a dataset to an entity/object. So, while you understand the code, the readability still takes a blow.
veryLongVariableName.Id = datasetVeryLongVariableName.Id
veryLongVariablename.Something = datasetVeryLongVariableName.Something
etc.
Using VB.NET's With keyword can help.
With veryLongVariableName
.Id = datasetVeryLongVariableName.Id
.Something = datasetVeryLongVariableName.Something
End With
Now, my question, is there any way of using With, or something similar, but for several variables at the same time? Something like:
With veryLongVariableName As a, datasetVeryLongVariableName as b
a.Id = b.Id
a.Something = b.Something
End With
I'm all for descriptive naming conventions, but they do tend to clutter things. Especially in VB!

I use the Call keyword when calling subs in VB/VBA. I know it's optional, but is it better to use it or leave it off? I've always thought it was more explicit, but maybe it's just noise. Also, I read this on another forum: Using the Call keyword is faster because it knows that it is not going to return any values, so it doesn't need to set up any stackspace to make room for the return value.

View 2 RepliesI'm still new in VB.net development environment, i've few of the question may need the advice from you guys to see whether i'm in the right track for the development as below condition:Basically my program wrote from this logics:
Condition:
2 log files available in C drive that is C:/BSKYB/Prod.txt
and C:/BSKYB_CWE/many of log files in .txt format
Program Flow:
Step 1: The program will read the last sentence Hexa number from the file "Prod.txt"
Step 2: Once the program detecting the keyword like example "abcde" it will go to another folder which is descript in C:/BSKYB_CWE to look at which text files contains the keyword "abcde"
Step 3: this step will capture the whole line the text info like example 1111 abcde
if in this case, once the abcde detected what is the command i should apply to capture the key word 1111 ?
This is the problem i have encounter right now, i doesn't know how is actually can apply the right method to read the whole text line once the key word is detected
Public Class Form1
' Const ConstBSKYB = "C:BSKYB_CWE.txt "
'Const ConstBSKYBP = "C:BSKYBProd.txt"[code].....
