Testing Vars In Intermediate Window?
Jun 22, 2009
Running through some basic tutorials and wanted the test the value of a variable i have created. How do I go about doing this in the intermediate window??
The only way I can do this is by creating a msgbox and then outputing the string var in the msgbox (var) to get the value I am after. Is there a way of doing this in the intermediate window??
I tried the following. but had no luck...
? ckstatevar
My code is as follows:
Private Sub ckboxDexter_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ckboxDexter.CheckedChanged
Dim ckstatevar As Single = ckboxDexter.CheckState
[Code].....

I'm looking into adding some unit tests for some classes in my data access layer and I'm looking at an update routine that has no return value.It simply updates a row based on the id you provide at whichever column name you provide.Inside of this method, we collect the parameters and pass them to a helper routine which calls the stored procedure to update the table.Is there a recommended approach for how to do unit testing in such a scenario?

I'm building an Active Directory wrapper in VBNET 2.0 (can't use later .NET) in which I have the following:
IUtilisateur
IGroupe
IUniteOrganisation
These interfaces are implemented in internal classes (Friend in VBNET), so that I want to implement a façade in order to instiate each of the interfaces with their internal classes. This will allow the architecture a better flexibility, etc.Now, I want to test these classes (Utilisateur, Groupe, UniteOrganisation) in a different project within the same solution. However, these classes are internal. I would like to be able to instantiate them without going through my façade, but only for these tests, nothing more.

I am interfacing my pc to a device called a MiniBee which is basically a usb digital output adapter to allow electronic devices to be controlled by the pc. So, I need to be able to individually address the output channels of this device, the only problem is the DLL supplied with it will only accept an integer value which represents a binary instruction if that makes any sense. I have basically got 8 public boolean vars OUT1, OUT2 etc that I need to use to turn on/off the outputs by them being set to true/false.
So there are say 8 digital output channels to operate and it has to work like this:
SetOutputs(1) would turn on output 1 and turn all others off
SetOutputs(2) would turn on output 2 and all others off
SetOutputs(3) turns on 1 and 2 and all others off
How to turn my public bool vars into an integer based on what is set to true/false if you get my meaning as there must be an easy way but working it out individually there are far too many possible permutations.

I want to learn visual basic, what book or books are the best to take me from beginner to intermediate?Would it be more advantageous to go through VB 2008 or VB2010 tutorials first or should i start with a book before going through VB2008 or VB2010 tutorials?I am comfortable with Sequel (SQL) language, learned on the job and am at the advanced level of Excel/Access writing formulas functions,etc. the next logical step is to learn VB.

I have a few SQL connected check boxes in my form.The problem is that on the 'Add New' event the check boxes go into a "intermediate" status (filled in).What I would like is for all the check boxes to be unchecked.I have so far tried the following and none of it worked.[code]Nothing seems to help, in fact there seems to be no effect at all on the check box properties no matter what I do (wether I change the property in VB, in the table definition, or programicaly).

after slicing and dicing, i got 2 vars with the following values in vb.net:
strTag = "<#<span class=SpellE>vermittler_person_Name</span>>"
tmp = "<#<span class=SpellE>vermittler_person_Name</span>>"
Comparing the vars gives a false:
strTag = tmp ' ==> false
Comparing the values directly right there gives a true:
"<#<span class=SpellE>vermittler_person_Name</span>>" = "<#<span class=SpellE>vermittler_person_Name</span>>" ' ==> true
Both are strings, i tried all kinds of stuff: string.compare, string.equals, also regex etc. etc. everything works perfect with all the other strings with simlilar structure, just not and only not with "vermittler_person_Name" in the middle...

I have a DataGridView that has columns with a value type of boolean.To load the DataGridView, I load values into a DataTable then set theDataGridView.DataSource = theTable What value can I use in the table to load an intermediate check state?
Would it be better to use a check box control with a value than to use a column set to the boolean data type?
The check box is for display only, and will not need to be changed.

from the vb web:
Quote:
The following Microsoft intermediate (MSIL) instructions throw OutOfMemoryException :
*
box
*
newarr
*
newobj
Does anyone knows what exactly does box means? and also is there anyway this statement will cause an outofmemory: Dim a As Boolean
What about if its just an empty object: Dim a As someobj

In need of some desperate help. Has anyone had any experience with a software product called Pres? The programme provides a function (userhook) that can run externally created dll's as the programme offers no COM support. The basic requirements for the dll are as follow.
1, The dll requires a public function named UserInstruction
2, The UserInstruction must have 5 parameters. The first and second of type long, the third a double array and the fourth and fifth parameters required type is a string.
This all seems pretty simple. But as .NET doesnt support exporting functions within a DLL to allow direct public access to the function through third party software it becomes tricky. After doing some research it seems as though this isn't possible in .NET. The only way I can see to do this is to convert the dll to Intermediate Language and play around with it once this is converted and then convert the IL code back to a DLL. I found this on the following site [URL]..After trying this when I try to use the DLL via Pres I am still getting no joy.

I have a File i need to read and extract a few values from each line in the file. my problem as it stand the file i'm reading has some unconsistatcys as all of the Strings are seprated by " " but the integers are not they are Without any Speech marks to define them. I have thought of a methord to deal with this but i can't for the life of me think how to achive this.
As the file has unconstancys to be used with a standard " " extractor, the only consistancy is that there is allways a " before the integer and after attached to another column. this could be used i thought.
a Sample of the data is only one line:

I have a Do loop that I want to exit once it goes through without making any changes to an object I created. I figured the best way to do this was to create a temporary copy of the object at the beginning of the loop and then compare that to the actual object at the end of the loop to determine whether any changes were made to it. The problem occurs when variables are accessed and copied by reference. I have tried to use some of the methods such as .Clone and .Equals (maybe I shouldn't be using these, but I didn't see any better built-in methods), but I seem to be doing some stuff wrong. Can somebody give me an example of a good way to copy an object for later equality testing, and how to do the equality testing?

I was once a VB 6 expert, but it's been a while.I am attempting to create a simple DLL in VB. I created a new WCF Service Library, which is what it looks like I needed to do. I filled out the interface and implemented it. Here's the interface:
<ServiceContract()>
Public Interface AgileApi
<OperationContract()>
[code]....
And attempted to call it, but I get System.EntryPointNotFoundException. I've tried pathing the defined library and copying the dll file into the same place where my EXE is, but no change to the error.

I'm trying to determine if a file "G:myfilesfile1.txt" exists. Using sample code from numerous web searches I can't make any of the FileSystemObjects work. Seems to me the FSO routines are an add-in to VB. If this is so, how do I add them in?
In noncode, this is what I really want to do:
if "file1.txt" exists AND "file2.txt" exists
if "file1.txt" filedate > "file2.txt" filedate
copy "file2.txt" to "fileold.txt"
