  Is there a listing of the various messages associated with exceptions available anywhere   I did a quick search on Google, but didn't find what I'm looking for.

Now I just want just make it so I can send the exe directly to people with out them having to install or anything but I don’t know anything about it. Can someone tell me or point me in the direction of a tutorial I can do. All help appreciated J Hi, In addition to that, VB6 is COM based (so as MFC, ATL, native C++, Delphi, etc...) they are using COM API's(dll's) on the OS.

• Visual Studio Tools for Office How can I insert and work with images?

  I have a program running on a linux server that serves out barcodes for reports. I created a web service in c# that grabs the barcode graphic from the server and returns a base64-encoded string of the barcode image the server creates. I want to insert this graphic in the upper-right hand corner of the word document and I'm thinking the header is a good place for it, but I'd also like to consider positioning a floating image as well. I've been doing some reading and playing around; By using a bookmark, I've gotten the grahic inserted in the header (the barcode graphic, once inserted should appear in the same place on all pages of the doc, ...Show All

• .NET Development How to tell if a column in DataTable (ADO.NET) is mapping to "image" type in SQL Server?

  Hi, everyone. I am using .net framework 1.1, VS studio 2003 and MSSQL Server 2000. I tried to write codes to clear all the image data in several tables which are stored in a dataset named myDataSet. As I know, the image type in MS Sql Databse is maped to Byte[] in .Net.  I used function GetTypeCode()  to compare the column type with the standard Byte[], but it doesn't work. Any idea thanks.   Following is my code: byte[] bt = new byte[100] for(int j=0; j<myDataSet.Tables.Count;j++)  {        for(int k=0; k<myDataSet.Tables[j].Rows.Count ...Show All

• SQL Server How to check for table existence before dropping it?

  Apologies if this has been answered before, but the "Search" function doesn't seem to be working on these forums the last couple of days. I'd just like to check if a table already exists before dropping it so that I can avoid an error if it doesn't exist. Doing a web search, I've tried along the lines of "If (object_id(sensor_stream) is not null) drop table sensor_stream" and "If exists (select * from sensor_stream) drop table sensor_stream" In both of these cases I get the error: "There was an error parsing the query.
