Visual Studio 2010 - .NET Function As String, Will Return False Be A Boolean?

Sep 21, 2011

I have a HTTP class that gets content from URL's, POST's content to URL's etc and then returns the raw HTML content.In the function inside of the class it detects if there is a HTTP error and if so I would like to return false but will this work if I have declared the function to return a String?

Code Sample of what I am trying to do (Note the Return Content & Return False if a HTTP error code is detected)Public Function Get_URL(ByVal URL As String) As String



Public Function Returns Boolean True Or False

Jul 28, 2011

I have a math program that I am working on. One of the exercises has a random word and 6 radiobuttons. The user has to select the radiobutton that displays the exact number of letters in the random word. What I am having trouble with is creating a Public Function to check if the answer selected is the correct one. The radio buttons are within a groupbox. The Public Function returns a boolean True or False.

Visual Studio 2010, Outlook 2010 And Windows Application, Return Emails?

Jan 5, 2011

At present I have wrote an application (in-house CRM, vb .net 2010) which allows me to send emails under the selected customer & I categorised these emails.As these are categorised I can return data to display email history in my program by using search criteria:

Dim oMail As Outlook.MAPIFolder = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail)
Dim sSearch As String
sSearch = "[Categories] = '" + "[" + tAccount.Text.Trim + "]" + "(" + tShipTo.Text.Trim + ")'"
Dim oItems As Outlook.Items = oMail.Items.Restrict(sSearch)

However the limitation to the above is it only looks at sent items & no other folder.My ideal solution would be to display all email correspondence for a certain contact.

Sql - Visual Studio 2010 Crashes After Pasting A Large Multi-line String (Approximately 1500 Lines)

Jun 4, 2012

I am creating a VB application in Visual Studio 2010 that installs some SQL stored procedures. These stored procedures are encrypted otherwise I would just supply my clients with .sql files to create the stored procedures.

.net - Boolean From Nothing Sometimes False - Sometimes Nullreference-Exception

Jan 26, 2011

coming from this question i was wondering why:


'this throws an "Object reference not set to an instance of an object"-Exception'


A CType(obj, Boolean) would evaluate to False(just as CBool(obj)), i think because the compiler uses a helper function, but that is not my theme. Why does casting Nothing to Boolean evaluates to False, whereas casting an object that is Nothing to Boolean throws an Nullreference-Exception? Does that make sense?

.net - Boolean VB Expression Returning False For Integer 1?

Jan 17, 2011

This is probably a really basic (no pun intended) question, but I can't seem to find an answer anywhere.Why does the result of func1 return False and func2 returns True? On every other test I have done, integer 1 is converted to boolean true and 0 to false. Works ok if I just set rtnValue to 1 or 0.

Turning A Boolean FALSE If The Right KeyData Isn't Pressed?

Aug 2, 2010

A week or so ago, you folks really taught me how to use the KeyData event. I adopted some of the coding to make my new code so much better. A few days ago, I thought I figured out how to run my little game. You see, you have two buttons. Comment and Uncomment. You Press Control + K and then after that, you press Control + (C or U) to activate the buttons. And I thought it worked! But my buddy figured out how to break it! The thing is, I need to figure out a way to make IsCtrlK (Look below) False if any key that isn't Control + C or U is pressed right after it. What would you suggest I look into using?

.net - Which Version Of Visual Studio 2010 Contains Visual Basic SharePoint Templates

Aug 5, 2011

Does anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.

At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates

Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?

Autocomplete - Visual Studio Intellisence Auto Create Function ()

Jun 1, 2011

In visual studio programming in Vb.Net you get a special autocomplete around functions. If you add a name in front of a statement the rest of the line is treated like function parameters.

strInEditBy dsInfo.Tables(0).Rows(0).Item("plandesc").ToString()

strInEditBy ( dsInfo.Tables(0).Rows(0).Item("plandesc").ToString() )

I wanted to add a = operator in the place of the ( but unless I type really fast it auto-adds the ( ). How can I turn that off.

Function Call For Multiple Textboxes Using Visual Basic Studio 2008

Feb 17, 2010

I am working to make a function that will update the back color of a text box based on multiple variables values. I can write the code to do the calculation, but I am not sure how to make the function realize which text box to update (as I will have about 30 different boxes). Below is the code that I have for each box so far, but I will have quite a few more, and would rather use a function to reduce the amount of code, and also make it cleaner as well.

If sngPreviousPrimaryPropertyTotal >= sngPrimaryPropertyTotalCost Then
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightGreen
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightRed
End If
[Code] .....

Or is there a way that I can tell the function that it's updating the text box that call the function in the first place? Say if txtBox1 has updated text and calls the function, then the function 'knows' to update txtBox1, but will update txtBox2 when it's called by txtBox2.

Visual Studio Documentation Should Have Examples For Every Method, Function, Event And Operator?

Dec 17, 2009

It is really too bad that Microsoft (who once had the best documentation in the business) has slipped so badly. Good documentation does not really require analysis, though, admittedly, it is a lot of work. To wit: for each and every single method, function, event and operator provide the following: a brief topical functional description including any parameters, a detailed description of how the object works, a workable example of the code needed to make this object do something useful and links to all possible associated objects (See Also).

I see pages upon pages of useless text and links to other pages full of links. This rapidly descends into a crevace of unbelievable complexity for the developer trying to find out something truly simple like filtering a DataGridView without changing the data connection. (As it turns out this is very simple to do but I could not find a single example of how to do it in the Visual Studio documentation.)

.net - Return A String Array From A Function Without Initialising It First?

What I would like to do is just return the string array without having to declare a variable first and then return the variable.Something like this, although this obviously doesn't work:

Return {"bar1","bar2","bar3"}

Is it possible to do this, I can't seem to find a method that works?

C# - Create A Visual-Studio String Visualizer?

Aug 18, 2009

I was trying to create a visualizer for IDictionary or ICollection Then like the simple visualizer (without dialog; I mean the ususal string visualizer that appears when hovering the variable, see image below), I want to make my custom text, I want to cast the collection to its type's list (I.E. StringCollection to List(Of String) or List) and then I will be able to see it in the visualizer. Or for Dictionaries show to lists visualizers for keys and for to implement or even how to start?This is something I thought about:

using System.Collections.Specialized;
using System.Collections;
namespace ConsoleApplication2


I want to use something similar for ICollection (or IList), IDictionary etc.Note that in arrays, the visualizer shows every nested objcet.This is actually what I want to achieve:Try to visualize a List and you will see that there is a private value _items, so you can see its items. I want to achieve something similar in collection and dictionary.
