VS 2005 - How To Use SetSelectedRowCore Method Of DGV
Oct 31, 2009
I am using the DGV to display some data, and it is read-only, and I do not want the user to be able to select any rows - i.e. it is not necessary or desired to show a particular row with the blue selection highlight. Internet searches point to the use of the SetSelectedRowCore method of the DGV, but this is a "Protected" method.

I have a piece of code that would be greatly reduced if a variable can be used instead of the actual method. (I am using a structure) kinda like the difference between the following code.
srrMulti.mthChildProp1.varRecall = strVarRecall
subPageRef
srrMulti.mthChildProp2.varRecall = strVarRecall

I created a reporting utility for my users to view, send (via email), export SSRS reports. I have set up date parameter boxes with calendar drop down and they are able to send via email a URL link that would either display the report via ReportViewer or send a link that would let then view the report in Excel or PDF. This is working just fine. Now I just added a button for adding new email addresses and a new windows form with a textbox for entering the email address and a command button for Save Email Address. I get an error msg Quote: Objects added to a BindingSource's list must all be of the same type.[code]

I know that with the Command Button, you can utilize the PerformClick option. I would like to know how you would go about doing something similar for a Combobox.What I am looking to do is open the Combobox within the GotFocus method.

I need a bit of advice. I am working on my project with the listbox. I know how to create a source to get the strings from the text file using ReadLine method, but I have no idea how to split the strings in the text file by on the third commas and ignore the other strings while select with the matched strings on the listbox for each row.Here it is an example listbox Here it is an example items on the listbox
random item 1
random item 2
random item 3
random item 4
random item 5
And here it is an example text file.
example strings one, any strings 1, any random strings 1, other strings 1, final end of strings 1
example strings two, any strings 2, any random strings 2, other strings 2, final end of strings 2
example strings three, any strings 3, any random strings 3, other strings 3, final end of strings 3
example strings four, any strings 4, any random strings 4, other strings 4, final end of strings 4
example strings five, any strings 5, any random strings 5, other strings 5, final end of strings 5
The listbox is display the list of an example items, so if I select the "random item 1" item on the listbox, it read the strings through in the text file on the first line to get the strings on the third commas in the same line which it is (any random strings 1) to split it while ignore the other strings (other strings 1, final end of strings 1) that come fourth and fifth commas. So, if I select the "random item 2" item on the listbox, it read the the strings through in the text file on the second line to get the strings on the third commas in the same line which it is (any random strings 2) to split it while ignore the other strings (other strings 2, final end of strings 2) that come fourth and fifth commas and so on...That is what I am trying to achieve by select the each listbox item to get the correct strings for each line in the text file that come on the third commas while to ignore the other strings.

I have a large problem with inheritance in vb.net. The problem is the following:
I have 2 forms => frmBase and frmChild
In frmBase i want to create a method Called StartWorking() and i want frmChild to inherit this method.
But here is the tricky thing: when frmChild.StartWorking is called i would like the following => without calling MyBase.StartWorking()
I want frmBase.StartWorking() to be executed first and after a test in frmBase.StartWorking if blnValue is true then frmChild.StartWorking has to be activated. if blnValue is false that frmChild.StartWorking cannot be activated.

I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.

When I am loading an Assembly dynamically, then calling a method from it, I appear to be getting the method from Assembly executing before the code in the method that is calling it.It does not appear to be executing in a Serial manner as I would expect. Can anyone shine some light on why this might be happening. Below is some code to illustrate what I am seeing, the code from the some.dll assembly calls a method named PerformLookup. For testing I put a similar MessageBox type output with "PerformLookup Time: " as the text. What I end up seeing is:
First: "PerformLookup Time: 40:842"
Second: "initIndex Time: 45:873"

Why does my the declaration of my string in the code result in the following error? Is there a workaround?
Code:
<script runat="server">
Protected Sub form1_Load(sender As Object, e As System.EventArgs)
Dim x As String = "</script>"
[code]....
Error: Statement cannot appear within a method body. End of method assumed.
Note: The following page did not fix my issue and instead resulted in the string </script> being output in my page. ( VB.NET hates </script> tag in string literal )
