Is There Any Reason To Use #if Directive
Sep 20, 2009I have seen in Debugging .net 2.0 Applications the following code [code] Is there any reason to use the #if directive? I mean, from what I understand the method will only be called if the DEBUG is defined, so I don't see a point in having the #if in the method body.

View 1 RepliesDesign Mode Preprocessor Directive Workaround?
Jul 12, 2011I know that there is no DESIGN, DESIGN_MODE, DESIGN_TIME, etc preprocessor directive value. However, I need something that can do the trick. I can't use a normal If statement, because in my case I need to change the inherited class so that the control renders properly at design time. If not, I'll receive an exception due to the fact that the inherited class is an abstract class.Here's what I'm looking to accomplish:
Partial Class MyCustomControl
#If DesignMode Then
Inherits UserControl
#Else
Inherits WidgetControl
#End If

Navigating Through The Recordsets?
Aug 23, 2010I am using Windows Forms on VB 2008 Exp. combining with Access 2007 as backend.I have designed a form to use ADODB connection with recordsets to retrieve and display data on label controls on the form.On the Form I have buttons like (First, Previous, Next, Last).... I want to use these buttons to navigate the rows of the recordset.However, I have problem in the codes - when I click the PREVIOUS button, it will tell me that either EOF is true. But if I click the NEXT button, it moves to the next record once.... Clicking on NEXT again, does not move to the next record..
See my code below:
Imports ADODB

Jan 29, 2012I have a multilingual company website (Visual Studio / VB / ASP.NET 4.0), and when, on the homepage, you click a flag, the text changes to that language and stays with you the entire session, after I made a class, BasePage.vb.

It's been recommended by @Aritstos to make it so it looks like clients.aspx?lang=nl as opposed to just clients.aspx in another language.
Currently, my asp homepage hyperlinks that work look like this:

Reading Excel With ADOBD Recordsets
Mar 5, 2009I am trying to read an Excel workbook with VB 2008. I am fairly successful but I need to make the code more flexible. Currently I use.[code]There are a variable (unknown) number of sheets within a workbook, all with the same format, and their names are given in "SHEET NAMES". What I need to do is now loop through these remaining sheets and transfer the data. I can do this into individual "cells" arrays but I would like them in one 3-dimensional array, something like sheets(sheet-number,columns,rows)I am new to VB and I'm not too sure about variant type, but any suggestions would be most welcome.

SQL Stored Procedure Doing Actions On Multiple Recordsets And Then Comparing Results?
Mar 23, 2011My experience with Stored Procedures is limited and I'm hoping this will solve my payroll problems. Further, for what I'm attempting to accomplish a Stored Procedure may not be the best answer.I'm attempting a Payroll function in which the goal of the Stored Procedure is to fetch the data for a given Payroll Period, do math on the first returned employee, output a calculated result, then move to the next. Let me explain a bit more...Based on a Pay Period ID which is given to the Stored Procedure, I would like it to do the following:Select the employee in that period, add a total of his hours worked, then add that employees total commissions, whichever amount is greater - return that value (along with the totals - such as the total hours and total commission) - then move to the next employee until completed.

Commandbuilder Not Recognized By Intellisense?
Apr 13, 2010i know someone will say this belongs in database programming but i don't think this problem is to do with databases and is more to do with visual studio.
when i start to type oledb.oledb..... intellisense would usually give me an option for oledbcommandbuilder. in the current program i am doing for coursework this option is not given. i can choose oledb.oledbcommand but i do not know how to use it (too advanced for A-levels, yes i'm british) if i actually type oledb.oledbcommandbuilder visual studio does'nt show an error in my error list. so what is going on? how can i get visual studio to recognise oledb.oledbcommandbuilder?

My intelliSense typing does not show MailDefinition. I get as far as Sytem.Net.Mail - but MailDefinition is not an option.I tried added a reference to System.Net (not necessary, but trying different things), still it doesn't recognize the class.
Question:Do I need to register a DLL or something? How do I gain access to class MailDefinition in my Form class?
EDIT:BTW: In object browser MailDefinition is defined as:
System.Web.UI.WebControls.MailDefinition
I get an error saying that UI is not a member of Web Does this mean I need to add this control? it's not on my Toolbox. Should I look for and register an OCX file?

View 3 RepliesHiding Form - Hotkeys Only Recognized Once
Dec 19, 2010I have a small app with one form (form1) which is supposed to be hidden until a hot key combo is pressed. I have read and taken sample code from: [URL]. I do have a keyboard class that hooks keyboard input, (I have my reasons) but it's odd that it will recognise the first hotkey and fire the event, but none after that? The problem is, I can make the form show, but not hide again. It will only recognise one shortcut, one time. How do I make it respond to another hotkey combo? Is the handle changing? Even with focus, the enabled form is not hiding again.
