I have a project I am working that requires me to go to an FTP port and copy a file to the local machine... so far so good... the next step is to take the comma delimited file and import the records (rows) into a local Access database...
Should I be looking the Attach method in Access? To attach and dump all the data in one shot?
OR To open the file with StremRead and process each row one at a time?

I have a Customer database table with a text field named customerPicture with the name of the JPG file.
I have made a Customer Entity class with the LinQ to SQL Designer.
I also have a FormView displaying Customer instance binding with a LinqDataSource.
My problem is:
I want to make some modifications when some control want to bind the customerPicture field.
For example, when my FromView want to show the field customerPicture I want to return not only the JPG file name, I want to modify this string to add the complete file path and perhaps resample the image to a determinate width and height.
I know that is posible to defeine a partial class named Customer to implement certains partial methods, like OnCustomerPictureChanged(), but I dont know how to do this.
If I make, in this Customer partial class, a new method, for example getResamplePicturePath(), how could I invoke it from a FormView?
I am working on Vs2005 and asp.net 2.0. I have a solution with 4 projects (business object, components, data access, webclient)When I change any existing method or property in Business object or data access, it is not reflecting in the application. I have deleted the existing references to the project and added them after the new build. I always get errors like "method not found or No overload method "It seems like old verion of dll is still there in the reference.

I am working on my company intranet and trying to integrate it with our existing MS Access applications.
I need to provide the ability to have the client click on a link/button from an aspx page and have it call a function in the MS access application to look up the corresponding record.
I came accross the thread [URL] but that is not really what I want as the ADP application will already be running on the client I just need to pass it a value.
Alternitively if I could start a new instance of the ADP passing it a parameter on open to find the correct record that would be a compromise.
Do i remove the ability to call a method from the class my page is inherited from?

I have a table with 4 columns: ID, signId, storeNum, quantity with ID, SignId, and storeNum as composite primary keyif storeNum is -1, that means the quantity is the default quantity. If a store has a store-specific quantity, the storeNum is this store's number.
I need to show all rows that have specific quantity for a store, and all rows that have default quantity and of which the store does not have store-specific quantity
currently I use table-value function with storeNum as parameter to return the list. first, I get all rows that have specific quantity for a store; then, I use cursor to loop through all rows that have default quantity and check each row if the store has a specific quantity. It takes 9 seconds to run the function for a store.
The function is called within a stored procedure, which in turn is called by a function in a class, which in turn is called by a aspx code behind file. It takes about 20 seconds to load the page. 20 seconds to load a page is too long. I am trying to improve
the performance.
I wonder if there is an alternative method to the cursor to get the second part of the list.

View 1 RepliesI access querystring values in each content page's pageload method to get Username and Id. Is there a way I access the querysting values from Masterpage's pageload method and each content page goes to Masterpage to get those values without creating any other local variables in content pages? I know this can be done with Session's or view state but I was thinking to reduce redundancy of accessing query string in each content page.
