• Microsoft ISV Community Center Forums Problem with Connection Strings

  Hi All, I have an excel spreadsheet, which I want to use like a database table and access using ADO from another spreadsheet, but whenever I attempt to assign my connection string to the ActiveConnection property of my ADODB Recordset, I get the following error: Could not find installable ISAM.

• Visual Basic Help! I can't save data changes to an MDB file in Visual Basic 2005 Express

  Hi all. I've created an application that will read data from an MDB table (linked to an Excel spreadsheet), but I during debugging I cannot actually save any changes made to the table. I've gone through all the walkthroughs but I just end up with an error message. Is it actually possible to write to an MDB file If not, how do I create an MDF file (which I know is writable) from an existing Excel spreadsheet Although I have created a version of this spreadsheet on my local server, VB2005E won't let me connect to my local server when choosing a data source. Clearly I'm a complete newbie at this, so all advice is very gratefully appreciated. Make sure that a primary key has been set on the table in ...Show All

• SQL Server NoRows SubReport

  Greetings, I have a report which contains three subreports. Each subreport is contained within a rectangle in the main report so I can force a page break after each subreport. In each of the subreports, there is a graphic and a text box on one line, then another text box below those two items, then a table below all that. My problem is that if one of the subreports returns no data, it is resulting in a NoRows sort of situation and not even the graphic and the two text boxes are shown. I understand that you can set a NoRows message, but ideally, I want my NoRows message to be the graphic and the two text boxes, not a plain text message. I'm not sure if this is even possible or at the very least if I could conditionally force a page br ...Show All

• Visual Basic Access database + BLOB?

  Hopefully someone can help me with a few questions: 1) Can you manipulate Access fields to manually (using the Access interface) add images translated into binary (have a text field instead of a OLE Object field) Or does this have to be done through a memorystream/streamwriter in a seperate program 2) I don't like using BLOB to read binary text streams from a database because it causes crashes when I scroll through the entries too fast or how it requires you to read the binary from the database to a physical file then read the file using system.drawing.image.fromfile(). Can I use image.fromstream() to do the same thing without having to write to the harddrive (I would like a short example please) Maybe memorystream 3)Can you strip the OL ...Show All
