Apply The Using Command To A SqlDataReader?
Dec 23, 2009I just want to verify something. I believe it is likely that if I apply the using command to a SqlDataReader, that it will both close the data reader and dispose of it. For example:
Using sdr As SqlDataReader = cm.ExecuteReader()
Dim someInt As Integer = sdr.GetInt32(0)
'other details and actions
End Using
Will that close the sdr SqlDataReader after it exits the Using code block. (I believe it will, but just want to verify.)

View 2 RepliesMake If Command Apply To More Than One Thing
Jul 29, 2009i was wondering if theres a way to make an if command apply to more than one thing, this is my problem: theres 9 white squares and if theres one or more thats orange, then a numer.text goes down one but at the moment theres 9 white squares and for every one thats orange the score goes down one, so if three are orange then the score goes down by three, or if five are orange then the score goes down by five, I'd like to make it so that even if there all nine the score only goes down by one.
View 13 RepliesC# - Prepend A Substring If The Source String Does Not Begin With The Same Substring?
Oct 10, 2011I'm trying to create a valid RegEx replacement pattern for correctly formatting specific .XML file names. Specifically, if a file name does not begin with a prefix, let's say, ACE_. If the XML file name and extension does not begin with ACE_, prepend the string ACE_ to the file name.For example, if my input source string is the following:
Widgets.xml
I would like to execute a single RegEx Replacement that would result in the string being:
ACE_Widgets.xml.
Conversely, if the string already begins with ACE_, I would like it to remain unchanged. Also,how can I include the pattern ".xml" to ensure that the string pattern for the file name and extension ends with ".xml" in the same matching pattern for the RegEx Replacement pattern? As for the match, I have some luck with the following:
^ACE_{1}[dD]+
Which indicates there is a match for the pattern if the input string is ACE_Widgets.xml and no match if the string is Widgets.xml
The RegEx pattern would suffice, but if you need to know the language in which I'd like to use the replacement pattern is in .NET 4.0 in either C# or VB.NET.
The following posting is close to what Im looking for, but with the inclusion of the *ix directory path prefix, and the use of preg_replace() in PHP, I'm having a bit of a struggle getting it to work with what I need to do:

Command Line Switches - Keeping Command Window Open?
Feb 24, 2010I am using the following code to run defrag and to analyze if the C: drive requires defragmentation:
Dim analyze As Process = System.Diagnostics.Process.Start("C:WindowsSystem32defrag.exe", "C: /a /h /u /v")
This process runs through analyzing, runs it in normal mode & prints the progress to the command window.
My problem is that as soon as the process is complete the command window closes. I need it to stay open so that I can read the results.

View 3 RepliesCommand Line Program To End Before Moving Onto The Next Command In Loop?
Feb 4, 2011I am using a CheckedListBox that is populated with Filenames (full path, i.e. C:TestTest.jpg)When I have the files that I want in the CheckedListBox I wish to click a Start Button which will process the list one at a time using an exe program that runs on the Command Line. There are arguments that need to pass to the command line as well as the file location in order for the program to process.I currently have it working but the issue is the loop finishes quickly and it is left up to the CMD.exe to finish the process. What I would like is for the LOOP to wait until each file completes processing before passing the command for the next file in the CheckedListBox.There some reasons I wish for it to work this way.
1) I would like to have a button that can Pause/Restart the Loop.
2) I would like to have a button that can Stop the Loop so the whole process can end.
3) I would like to have the Loop remove each file one by one from the CheckedListBox after it has been processed.
4) I would like to display a Message once all the files have been processed.
5) And if it were possible I would like to report the status either by text or a progress bar showing where it is at in the process.
6) And the ability to add some error handling if possible.
Since the Loop finishes so quickly as it just passes the command to the command line using the & as a seperator it is the command line that is handling the rest of the process. Because of this there is not control over it in the GUI.The code I am using allows the Command Line text to display in the Form so it won't open up a seperate window to run CMD.exe. This is the desired affect as I would like everything to appear to run from within the Form itself.

Insert Command Not Functional After Clear Command In Vb Report
Aug 21, 2011User need to select their prefferable data to show in report. What i did is i have a clear command first to delete the temporary table. The temporary table is basically a table to stored user selection parameter data. After the clear command, i have
a insert command to insert user selection data into the temporary table. What happened now is when i run the program exe, first run of the report is work fined, but not the second and the following times of execution. It will return null or blank report. The weird thing is when i execute it from development environment, it seem like the report is able to pick up user selection parameter and run the report for the first times and the subsequent execution.

.net - Substring And The IndexOf Function

I have this problem that I'm going in circles on. The error message is "no accessible IndexOf can be called with these arguments."
My professor said that "to search for the string Los Angeles and substring will return it from the textbox, but it needs to know what position to start returning a word at, and that is where the IndexOf comes in." Does that mean substring and IndexOf are used together? That's what I did and may be the problem. Here's the code:

BindingSource Sort By Substring
May 4, 2010I want to sort the binding source column (Product Code) which formatted like (AA-AAA AAA AAAA)
but i do not want straight sort on product code column, i want the sort as :
substring of 1,2 + 8,3 + 3,3 and then the rest of the column.
I know i can do it in the table direct using the OrderBy and the substring function, but the problem is that sort is not static it is dynamic according to different status means it change the substring order.
