VS 2005 - SQL And / Or Queries From Variables

Feb 12, 2011

I'm in the middle of a project, I've got the bulk of it working but I cannot work out how to get my variables to modify the SQL query properly, I'll try and explain. GUI has 5 search fields Q1, Q2, Q3, Q4 & Q5 with 4 checkboxes that denote AND / OR operators that need to be inserted into the query correctly. If they are all set to 'AND' it works fine. However if the user wants 'Q1 AND Q2 OR Q3' then it fails. If I hard code then I just user brackets ie '(Q1 AND Q2) Or Q3'. For some reason I seam incapable of working out the code to achieve this...

Code snippet:
'Check AND OR Checkbox and assign Operator
If Q1AND.Checked = True Then
Q1Op = "AND"
Else : Q1Op = "OR"

VS 2005 Global Functions And Variables Within Solution?

Jun 23, 2009

I 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?

VS 2005 Multiple Forms And TextBox Too Many Variables?

Nov 15, 2009

I have 10 forms and say 5 text box's on each one so a total of 50 of these text box's. But the program is only using one of these forms only (user selects the 1 Form out of the 10) so I was wondering can these forms Share the input text box's? I am thinking NO, if so then the only thing I can do is just use 5 shared variables that all the forms can utilize.

VS 2005 - Localization In Windows Application - Label Which Text Is Merged With Some Variables Or Object Properties

Sep 2, 2010

I've implemented the localization in my windows application with no problem for the label or command button which have a fixed text.

My problem is related to the label which text is merged with some variables or object properties.

E.g.: vb label1.text = "There are " & myDataGridView.Rows.Count.ToString() & " items"

So, how can I set (if it's possible) the localization for these labels? I've this kind of assignment in modules and not in the form. It's possible to set a resources file also for modules?

VS 2008 - Take A String Of Variables With A Common Delimiter And Break It All Back Out Into Separate Variables

Last year (2010) I came across a FANTASTIC command that allowed me to take a string of variables with a common delimiter and break it all back out into separate variables (possibly an array) with one statement.

[Code]...

As long as the delimiter was a unique specifiable character, this one-statement command could break it out into elements. my memory and point me in the right direction.

Passing Multiple Byref Variables / Variables Fail To Change Calling Funct W/ Invoke

Sep 27, 2010

I have code, shown below, that works all except for 1 thing: The variables being passed byRef get passed, but once modified in the else section of the "if me.invokerequired" code of RecordData, the variables are never updated in the calling function. To reiterate, the calling function does not receive the updated data that is in the variables custid and amt.When debugging, I see the data change in the else section of "if me.invokerequired", but once it returns from the callback the data is missing.[code]

Define Some Global Variables Of A Class - Variables Occupy Memory?

Mar 23, 2012

I define some global variables of a class as follows:

Private Class MyClass
Private var1 as Decimal
Private list1 as List(Of string)[code].....

But I found that after this form is closed, all above variables, var1, list1, list2 still exist in memory. I thought they should be collected by gc since the form is already disposed as I confirmed.

Add: I have monitored half an hour after the form is closed. But these variables are not collected by gc. I have an automatic update procedure on the form which uses above variables.Since the above variables still hold values, the automatic update procedure is always called which causes exception. (One quick fix is to check if form.isDisposed in update procedure. But I do not think this is elegeant. Besides, these variables occupy memory.)

Multithreading: Reading/setting Variables, And Passing Variables?

Mar 8, 2011

Question 1: What is the difference between "Background Worker" and "Worker Pool" as indicated within the MSDN samples provided.

Question 2: I noticed while using, AddressOf _Function_, variables cannot be passed; what would be an efficient solution to this?

Question 3: While using multithreading is it required to invoke before setting variables, or only form properties?

Question 4: While using System.Net.Sockets is it safe/efficient to use Application.DoEvents while waiting for new data; or would be using a Do While loop be fine without DoEvents since the action would be multithreaded? Note: there can be up to 2000-3000 sockets in use at a time.

Possible To Use Variables Without DIM?

Jul 10, 2011

Is it in VB.NET possible to use variables without the need of use DIM? Now I have to use the variables like this:
dim a = 100
dim b = 50
dim c = a + b

I want to be able to use vars in this way:
a=100
b=50
c=a+b 'c contains 150

I think in VB6 and older VB this was possible, but I am not sure.

Asp.net - Using Session Variables In IE?

May 14, 2012

I have an ASP.NET application that I am developing. I'm using session variables within the app.In Firefox & Chrome, they all work.But in IE (ver 9), there's one variable that's not working. I'm not sure if it's a storage or a retrieval (or both) at this point. The variable in question that I'm storing is a List(T) type. It's the only one of it's kind that I'm using. Can't help but think there's a correlation there.One other old post mentioned the possibility that cache is causing the problem, but I didn't understand the answer very well.

Dim Rec_IDs As New List(Of String)
Rec_IDs = Session("Rec_IDs")
and
Dim Rec_IDs As New List(Of String)

Get And Set Environment Variables?

Jan 9, 2009

We have a couple of applications at work that need a reference to the license server set in the User Variables under the Enviroment Variables on the windows xp client machines(system properties, Advanced, Enviroment Variables). The problem is that both applications needs a reference to the same variable name and you can't have two with the same name. What i intend to do is to create a simple windows application with a button for each application that deletes the variable item present, adds a new variable item with the value needed for that application to be able to run and then run the application itself. This is just a temporary fix until we get a more permanent solution. The 'GetEnvironmentVariable' class in vb is not able to add or delete a item, maybe the WIN32 API could do the job.
