I have some code with a connection string going to a mdb, the query looks correct to me and I know that the data stored in the table exists but when I run the query in my code it says: No data exists for the row/column.
[Code]....
It has crossed my mind that perhaps the way the data is put into the program is not compatible with the data in the database, I don't know if that is a valid thought though.
I am having a slight problem with a feature I am trying to get working on a website I am doing. I keep getting the "No data exists for the row/column" error. And the problem appears to be with this line of code:

In ASP.net MVC 2, I can use routes.RouteExistingFiles = true; to send all requests through the routing system, even if they exist on the file system.
Usually, this ends up hitting the "{controller}/{action}/{id}" route and throws an exception as the controller cannot be found.
I do not want to use that route though (I have only a few URLs and they are specifically mapped), yet I would still like to prevent access to the file system.
Basically I want to Whitelist pages using IgnoreRoute. Is there a built-in way to do this?
My current approach is to still have a route "{*anything}" and generate a 404 when this is hit, but I'm just wondering if something is built-in already?
I would like to check whether a folder exists or not if not create. I'm sure this folder exists, but for some reason I get "false" when I check with "Exists" method.
The only reason I think could be because of the W: drive? I moved this application to production site and even there it returns false.
while I'm type in Windows explorer on my localhost and on the server "W:/Webs/ASPPages/cropper/uploads" it opens this folder. So my localhost and IIS server has W: mapping.
for test I tried to create the folder then it says can't find the path...
userFolderName = @"W:/Webs/ASPPages/cropper/uploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried "W:\Webs\ASPPages\cropper\uploads"
DirectoryInfo dirInfo = new DirectoryInfo(userFolderName);........

View 6 RepliesI want to retrieve a single column from a table in a database(ms access) and then the value retrieved has to be converted to a string!!
View 4 RepliesI have seen a lot of things on the net on this but nothing seems to work. I have a GridView with name and other information on files stored in a database but also on a Server. I display the gridview with the files and the user selects the file to delete (row) by hitting the command field for Delete. I have an event on the gridview for code behind. Here I want to access the file name for the row selected, to be able to include it in the File.Delete statement.
Even before this I want to display the selected file name in a label back to the web page. I have tried everything including findcontrol selectedValue, etc. Nothing is working. I either get complier error, or nothing is displayed in label. If I let it go the the File.Delete step I get access error becasue there is no file name. HELP. here is screen shot of the gridview. Ignore the download button for now. That is my next headache to figure out. So based on the screen shot I want the value of log_doc from the gridview. It is in a column called file_name
File ID
File Name
Log

I have a gridview with databound fields with a checkbox for each row. Only the check box is not bound to any field in the database. I have a button outside of the gridview. By clicking the button, I am trying to get the values of the partyID fields for all the rows that have the check box checked.
Upon clicking the button, nothing gets displayed but no error either.

I have an access 2007 databse (.accdb) connected to vb 2008 using (using visual basic) "create data source" and has a table called orders on a form, I have the datagrid view of Orders table with a column called cost (£). I need it to add up all the values on this cloumn and show on a textbox.and in most cases the column would have new data so i considered using a loop, taking each value and adding them. I did not hard coding any connection strings to connect to the rest of the program except the one provided when creating the data source.
by the way, I've used filter functions so does this mean that it would add all the values in the datagrid or would it add just the filtered values?
I have a database for a shop. Now I have run into problem when I'm adding products. I have a page where i add general info of the product that will be adding to the product table. Then I should have a page where I can add colors and sizes and so on. But how do I do that? When I add the product I set a price in the productdetail table and colorId and sizeId is sett to null. If I add a color to the table how do I do this the easiest way? I will not have a product where both colorId and sizeId is null. I have this SP and table structure. Then I'll do the same when I add sizes.

how to access the first row and first column of a sql table
View 6 RepliesI have a Table, which contains a list of league players. Each season, we record their Points per Dart. Their total PPD for that season is stored in other tables and extracted through other queries, which in turn are imported to the master table "Player History" at the end of the season for use as historical data.
The current query retrieves each players PPD for each season they played, when they played last, and how many seasons played.
The code for Last season Played has become too long and unstable to use. it was originally created, and split into two separate columns because a single SQL was to long. (LSP1) and LSP2) which work, but as I add seasons, Access does not like the length of code.
In short, i need to find a more simple code that will look at each row, and look in that row for the last non null cell and report which column that last non null value is in.
So if a player played seasons 30 & 31, but did not play 32..but did play 33, the Column with the code should be titled Last Season Played, and for that Player, it would state "33" in that cell, indicating that this player last played season "33"
In grid view I want to sort the particular column. For that we have to access that column
How to do this??
i have a grid view and i use TemplateField.
when i am in ItemTemplate all the column (7 column) are label so it fit to the current screen
by when i use EditItemTemplate or InsertItemTemplate the coulmn don't fit the the current screen and
i have to use the ruler in order to see more information about the cell (which is ok - because in each cell i have a dropdownlist or long textbox)
but when i drag the ruler to the right size to see more information only the cells are moved but the header coulmn stay so i see the current coulmn with worng header coulmn
