VS 2010 Identifying Bytes Vs Integers When Passed Through A Function

Sep 20, 2011

My issue is regarding overloaded functions of the already provided IIf function that would handle specific types. As you all know the IIf function provided returns objects, rather a specific type so for my needs I created a few overloaded function to do just that but with a specific type in mind. So having said I have IIf functions for types of booleans, strings, bytes, integers, etc etc.

Now my problem is when I'm trying to pass a byte value to this function that would return one of the two byte values. When I do this the designer keeps confusing my values as an integer value and calls for me to convert it to a byte. If I did this then it would defeat my entire purpose for creating these functions-which is to avoid any conversions. The only way I can solve this is by converting the whole statement itself or the true/false parameter parts individual to specify to the designer that these values are bytes. I'm just hoping there's a way of identifying the difference between bytes and integers..

Empty User.Config File Causes Exception?

Sep 13, 2007

Somehow the User.Config file was corrupted for an instance of my VB .NET app. When access one of my user level config property (My.Settings.MyProp) I get the a ConfigurationErrorsException with the message "Configuration system failed to initialize." I looked at the User.Config file and found that it is empty, it can be opened but there is no XML text contained within.I would like to programmatically fix the file if an exception is seen. When I attempt to use any of my user level properties, I continue to get the same exception. I've tried calling the Reset() but that yeilds the same exception. I then tried Save() to see if it would write out a default version, but it appears to do nothing (the file is not updated). My.Settings appears to be useless at this point.How can I reinitialize the User.Config file to the default config settings without deleting the old file? I would think that there should be some mechanism for restoring this file back to its default. And how can I update/reinitialize the My.Settings instance so that I can access the properties normally?

IDE :: [ASP.NET] FormParameter/ControlParameter Empty When Using Web User Control

Jan 14, 2011

I'm building a live search inside our web application. But now i have a problem with a Web User Control where i can`t find a solution for.

I`m creating a User Control Search which later will be used for a default live search. Now i have created the solution inside a ASPX page without a user control. This works fine. But when i replace the code into a ASCX file (User Control) the input inside the textfield could not be found. No exception but the input of the function is nothing.

how to get the controlparameter or formparamter to work inside a user control? I already have tried things like ClientID this results into a exception (control not found). The fieldname with the $ instead of the _, this results into the input is nothing.

Prevent The User From Proceeding If A Specific Text Box Is Empty?

Apr 19, 2012

I am trying to prevent the User from proceeding if a specific text box is empty. All of the following lines of code SEEM TO work:

If txtTitle.text = "" Then.....
If txtTitle.Text = Nothing Then.....
If txtTitle.text = Nothing Then.....
(followed by a message box advising of the need for input)

The problem is, if the User enters a space (either accidentally or intentionally) all three of the above recognize the space as a valid entry.

VS 2008 Let The User Be Able To Drag A Picturebox To One Of The Empty Pictureboxes?

Mar 17, 2010

I have an application where I have different picture boxes which the user can drag and move.I also have different empty pictureboxes.

What I want to do:I want to let the user be able to drag a picturebox to one of the empty pictureboxes. Also, If the user drags a picturebox to an invalid place (outside the bounds of any of the empty pictureboxes), the dragged picture box should return to its previous location.

So what I currently have is the usual drag-drop code and on the MouseUp event, I run this code (currently only checking for one empty picturebox):

If Not pbEmpty1.Bounds.Contains(Me.PointToClient(pbRemote.Location)) Then
pbRemote.Location = OldLocation
End If
(pbEmpty1 = Empty picturebox, pbRemote = picturebox that is dragged)

But it doesn't work, it doesn't care if the picturebox is inside the bounds of the empty picturebox or not, it still returns to its previous location...

How can I identify the items in the table that fall after a particular time of day? More specifically, I need to identify which of the data fields have a time after 14:00 on that particular day.

Design - Pass User Details Between Objects?

Aug 16, 2010

I'm redesigning an old VB6 application into VB.net and there is one thing I'm not sure on the best way to do. In the VB6 application whenever we created a new instance of a component, we would pass in the user details (user name and the like) so we new who was performing the tasks. However, no that I'm redesigning I've created some nice class designs, but I'm having to add in user details into every class and it just looks wrong.

Is there a VB.net way of doing this so my classes can just have class specific details? Some way so that if my classes need to know who is performing a task, they can get the information themselves, rather than having it passed in whenever the objects are created?

<controls:customerForm ID='customerForm' showBankDetails="no" runat='server' />

But I can't work out what to do with the showBankDetails variable in Code Behind to stop it from rendering that section, or simply hide it with a CSS snippet.How do I access that variable in the code behind using VB.NET?

VS 2010 Suppress Empty New Row At End Of Dgv?

This unfortunately adds a 71st row (the placeholder for a new table row).

Here is the code I use to create the 70 rows:
