View 2 RepliesVS 2008 - Detect 404 For File Download
Jun 2, 2010I have a webapp where a datagridview is populated with records from a database and one of the columns is a download link to download the zip or exe file. We have the zip files on our server, but not the exe files as those are on another department's server. We have all of the file available for download, but if the user as an option selected in a dropdown, those url's in the gridview are re-formatted to be the exe file's on the other dept's server, however they don't have all of them (some 20% are missing) which means if the user click's the link they get their server's 404 not found page and can't download the file.
My PM (Project Manager) is asking me if I can have our webapp detect that the file doesn't exist on their server and instead of them getting the 404 page, they don't leave our app at all and get a javascript popup window or the page is refreshed with a red mark (and a message) next to the link they clicked on, is something like that possible? I have 2 restrictions with this, I can't modify the database because it doesn't contain file paths, it only contains a small portion like (Clinton County, Eaton County, Traverse County, etc..) and the rest of the url is formatted on the fly when the page is rendered, so there's no way to mark the missing files and there's no way we can host the files.

Apr 5, 2009I have roughly 20 text boxes on my form,When you press tab, it naturally selects all text in the box (highlighted in blue), so you can press any key, and it replaces it with that,That result is what I want, unfortunately, if you click into the text box, and tab back to it, it no longer selects all the text.I'm wondering how I can detect the tab event properly,I've tried adding a 'KeyDown' event to each text box, and then selecting the text, but the sub never runs, also tried detecting the tab event in my Main Form, thinking that perhaps the parent handles it and will receive that event, but.. No.I've thought of using an event like 'Activated' however, it will also run when the mouse is clicked.

Nov 2, 2009i have a two-dimensional char array that holds the values of a tictactoe board.Each element holds a value of either 'X','O', or and you can access the values with something like TicTacToe[0][1]with the first bracket containing the row # and the second containing the column #.
Whats the best way to detect the winner of a TicTacToe game? I was thinking about just making a function like this Private Function checkWin(Byval TicBoard as Char[][]) as Integer 'Return 0 if no winner, 1 if Player 1 wins, and 2 if Player 2 wins End Function Any ideas? I want to avoid using 8 if-else statements since that seems pretty inefficient and sloppy
[2008] Connect Four Detect Winner?
Jan 6, 2009In our program we track the moves in arrays by columns 0 means empty, 1 means black, 2 means red so it would look like this for example
column1(0) = "1"
column1(1) = "2"
column1(2) = "2"
column1(3) = "1"
column1(4) = "0"
column1(5) = "0"
for column 1, and we have seperate arrays for each column (7 in all) but they all have the same values 0,1, or 2 so how can we make it check the arrays and their values and detect a winner?
OLEDB Connection - Pull Information From Three Different Database Tables And Compiling The Information Onto One Screen
Jun 9, 2011The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

Method Which Check If A Certain DSN Exists Then If It Does Extract Information And Use Information For Connection Purposes
Feb 2, 2011I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?
Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _
lpSubKey As String, phkResult As Long) As Long
Goal: Find information on how to implement a method which will check if a certain DSN exists, and then if it does, extract the information and use the information for connection purposes.
