View 6 RepliesI have a page within our site that allows admin users the ability to upload configuration settings into the system instead of submitting 1 at a time.
While testing yesterday, i found that one of the upload pages allowed me to upload a excel file that had alot more columns than expected and when i checked the database, the first few columns that were expected took the values from the file, and everything else was ignored, but wanted to see if there is any way to check the number of columns in the file to make sure it matches the upload logic before accepting it.
I need to be able to have a user upload an excel file, then immediately work with that file and save the contents in a database.

I have a project using vb.net with mySql and mySql.Data.dll as a link to the database. Now when I test my website from local computer and with live server connection string all works fine. The thing is, when I upload my files to the server, it gives me an error Object reference not set to an instance of an object.I have copied the mySql.data.dll file to the bin folder of my domain and the query that gives the error is a basic insert statement that works from the local machine to the live database.
View 1 RepliesWe have the data in excel file and want to upload the same into Oracle table.To achieve this we are using following query
insert into [ODBC:Driver={Microsoft ODBC for oracle};connectionstring].tablename (select * from sheet$ )
This is working fine for less records but when the record count increases following is the error faced. Error : System Resource Exceeded
We tried the following:
1. We tried to remove connection pooling for oracle.
2. We tried to remove connection pooling for excel.
3. We also verified that only one connection for each (oracle and excel) is open.
Our assumptions:
1. Either the server setting is the issue
2. Jet oledb Driver is the issue.
I read a lot of tutorials to learn what was the way to manage accessdata on a MySQL database from my ASP.NET, but there still something to whichremains unclear is the formatting of data and the ideal time to do so.For example, if I have a sentence like the following:"Je voudrais t'aider à résoudre ton problème"
When I pass the variable that contains this sentence, I wonder who the quotea problem because the SQL query in this setting look like this:"'I want to help you solve your problem'The quote of "t'aider" comes as the end of ther string in the query string. So I have to the format the string to double the quote to be able to pass it in the database..Maybe I missed the good tutorials, so if you have any links
"SELECT a.fibunr, " & _

I've created a connection to a read only Oracle database but when trying to execute a very simple SELECT statement it generates the following error:

The page works if I write: where LetId=4 instead of @0. But if I leave the variable I get the following error: The column name cannot be resolved to a table.

View 1 RepliesBelow is our error message. This happens around 5 - 7AM daily, and we are struggling with identifying the root cause. It's hard for me to believe it's code related, but anything's possible. Still, what's odd is the app runs fine for a day then an IIS reset is done and everything is fixed. Is there any way this could be related to code and has anyone dealt with this error before? Could a job or some permission being run behind the scenes be using this same dll and cause it to be overwritten?
