Defining A Name For A Variable Range Size?
Feb 18, 2012
I have to define a name for a varying-length column of cells. The name is used later to define the range for a Data Validation List. I just cannot figure out (and the Help Function isn't assisting) how to define the Name, say "DropOrdNum" using a variable as the address for the last cell in the range. It is easy to define a name for "O13:O2000" - no problem, but then I have a whole lot of blanks in my drop-down list. But how do I define a name for "O13:LastCell", by making "LastCell" the Range Variable (am I correct in this) for the address of the last cell in the active range and then defining the name "DropOrdNum" as being the range "O13" to either "O(the row number of the last cell)" or "LastCell", being the address of the last cell in the active range, which varies by the hour?

I am getting the error:"Range variable 'sender' hides a variable in an enclosing block or a range variable previously defined in the query expression."for this

I can select any other item from the table without the error. "sender" has the same properties as "receiver" in the SQL table.

Im writing a program in VB.net that consists of three main steps:STEP 1: Display the source code of a webpage that is streaming a movie on it in textbox1.STEP 2: highlight the URL to that movie in the source code, and then display just the URL in textbox3.STEP 3: Download that movie using HttpWebRequest and HttpWebResponse to a user defined directoryThe problem is that i dont know how i would go about extracting the URL from the source code effectively. maybe i could try searching the source code for the string ".mp4" or ".avi" or other video extensions, but that would only find the end of the link, how would i highlight the whole link?

Notice the catch (Type) instead of catch (Type myVariable). Is this possible with VB.NET, or do you always have to declare a variable when you catch exception types, like so:

I know that there is a way in which you can generate any random number between any range using the random variable. But my question is that is there any way to do the same thing but with letters?

So I created a loop that collects data from the user that runs for a time dictated by the user. It then stores all the data in excel and outputs a graph.The problem I am having is that I cant seem to figure out a way to set the range of the graph for the points taken.since it runs on a loop i have i = i + 1.where the the output into the excel file sequentially writes to the next cell [code]which doesnt seem to work like I would have hoped.Also, there is one other thing that my program keeps doing that I cant seem to figure out.One of the outputs to the excel file is decimal number, it shows perfectly in the textbox, but when I export it to excel it rounds it to the nearest whole number.[code]

I have a datagridview, with 3 columns, each containing dropdown filters (in the column header). Of the 3 columns, 2 are working perfectly fine, but whenever I try to filter the 3rd column, it gives me this error: (Also all of the column's have the ColumnType property set to: DataGridViewAutoFilterTextBoxColumn) "Index was out of range. Must be non-negative and less than size of the collection. Parameter name: index." The error points to the part that begins with "If dgv1.Rows(e.RowIndex)..."

I am creating a virtual on screen keyboard similar to the windows on screen keyboard. I dont know how to make buttons that change its size with window size as it takes in place in windows on screen keyboard (osk.exe).
I also wanted to know if there is a way possible that could enlarge the buttons nearby the mouse cursor and recede & diminish the size of the buttons away from the mouse. And how to attach dictionary with it as in windows on-screen keyboard, like it shows the possible words we could type.

I have a label in my Form which on loading, displays the contents of a text file. The contents of the text file may change and if so, the number of lines also will. I would like the Form to automatically resize itself based on the number of lines in the file. If there are more lines that the size of the label can take, I would like it to either resize or show scroll bars.

I've been working with a CMS called InsiteCreations 2008. I'm running into an error I just can't wrap my head around. I would even be willing to compensate anyone a small amount over paypal, for a solution. The error is rare in occurance, and appears when clicking about 3-4% of links to other pages within our CMS.The full code page is quite large, but there seems to be only one function associated with the error. The error also only appears when not logged into the CMS. If logged into the CMS, clicking the link simply displays the page as normal. I have already checked permissions on the page from the CMS admin console, and it is public.
The error message is as follows:
Server Error in '/' Application.Collection index must be in the range 1 to the size of the collection.
Description:
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Now all went well about from using the structure correctly. The working of the structure was perfect. How ever i missed Two important issues. The structure needed a fixed size of 10 items (9 in programming terms starting from 0) And also out of the 5 items allowed to be chosen as one of the member types for the structure a limit of 5 items of that particular type.

I am not too sure about the syntax , since I am still very new to VB..
So this is what I have in a class
Code:Public Class DocumentDelivery Implements IDisposable Public Shared RenderList As New List(Of Byte()())
Public Function Initialize(ByRef env As et.User.SystemCommon.Environment, ByRef errs As et.Exec.Utilities.ErrorCollection) As Boolean
[Code]...
I didn't write the existing class, I am just making changes to it. I am not sure why there is no constructor. However, Intialize() is called every time a the class is created.Right now, I set the default capacity of the RenderList, (the class variable) to 1 in Initialize method.
Is there a way to set the capacity outside of the initialize method? what is the syntax?
