Our application is using VBSQL.OCX on Sql server 2000 to create temporary tables and load pipe delimited data from a text file with predefined format into the tables. It is failing intermittently doing this. 99% times it works perfectly. But on occasions it does fail with error. Once the process is rerun with the same input file it runs successfully.Basically the architecture is of Store/Head Office where there are around 200 remote stores sending set of data files to the Head Office. At HO our application sequentially processes each store which has all the set of files received, creates a corresponding table, loads the data from the file into the table and moves onto the next store.If it is for some reason not able to load the file for a store, it gives a failure message and continues with next store.Error which the OCX throws is "Attempt to convert data stopped by syntax error in source field"

or store all the chunks in one variable together and then when I need access to the chunks get the location and size of them and use that to find chunks each time I need to modify them.

I got this strange behavior when I try to access the TCHAR data variable in VB.Net code.There's a C++ native dll function which returns the data value in TCHAR*. Now When this function is called from VB.Net application I get only the first character of the returned value.
Suppose the return value from dll function is "Hello World", I get only "H" in the VB.Net application. I tried to store the return value in String variable also in StringBuilder, but I get the same result.

View 8 RepliesI want to take the data gained from a button press on one form and take that data and display it on another form. So it's like whenever the button is pressed
Score = 0
Then I want to transfer that data to another form into a label. I have VB.Net 2003.
I have a form with a listbox that when the form is opened I need it to display info from a file. I don't know what would be easier to work with Excel or a txt file, but it is in this format:
Phillip Frank
3/19/1990
3
999-555-8618[code].......
I would like it to populate the list box when the form is loaded, but if I have to use a button to tell it to load that is fine also.On the same form I have 4 textboxes that ask for each of the above items (name, DOB, Level, PH#) and a button that when pushed I want it to save it to the same file where the above info was pulled from in the same format.The Show Contacts button doesn't have to be used if it is not needed.
lets say I have:
arecord.name = "A"
arecord.value = 15 ' a number of type "long"
'
I then
call records.add(arecord,arecord.name)
' so far, so good but lets look at the next record
arecord.name = "B"
arecord.value = "this is text" as opposed to a number of type "long"
'can I then
call records.add(arecord,arecord.name)
I have a table with two columns (id and number1). How can i get from the datagrid or the dataset the data of one column (number1) in one variable?
