• .NET Development Interop layer throws System Exception (cast) when accessing unmanaged COM code

  I would appreciate help/comments on the following... I am trying to access a COM component written in Fujitsu NetCOBOL from C#. I have spent many hours (days...) reading the docs, trying various combinations, and looking at the samples but my attempts are failing miserably. The COM .dll is called "AVSCOMSVR" and the embedded TypeLib has been picked up and converted to an Interop Assembly by VS 2005. Here's a picture of the generated interfaces and Classes: http://homepages.ihug.co.nz/~dashwood/dashwood/AVSProject2.jpg I find this a little puzzling... VS2005 seems to have duplicated the interfaces, some above the Class entry and some subordinate to it, but that may be OK and just reflect my limited understandin ...Show All

• Visual Studio Supporting 2003 version of compiler and runtime in VS2005

  Hi, I have a question regarding C++ projects created with the 2003 version of Visual Studio. For the most part I have been using VS2005 but I still keep VS2003 since I haven't migrated all of the codebase. The reason for it is that some projects link to code which is not managed by me and I cannot get new versions of those libraries. My question is is there a way of using the old C++ compiler and libraries from the 2005 IDE, that is without converting the project files. I was the Makefile project and I am wondering if I could set it up to with with the old tools, or if you could give some other advice it would be great. Regards, Angel Kafazov AFAIK no, there is a tool named MSBee but it is for VS 2005 building .NET 1.1 managed applic ...Show All

• Visual Basic Visual Basic 6.0 and MS Access linking pictures!

  Hey all, im a student in a UK college, using VB for my coursework in computing. Basically, i can't get a hold of the code for something which i think is important in my project. First, let me put it into context, my project consists of a program for use in an opticians, so "stock control" is one of the forms. Thus, i have a database of the available spectacles, linked to the form via an ADO control. My intention was to place images in the database, then have a set space on the form in which the image will change according to the record. E.g. if i move "next, next, last" the image would correspond to the last set of spectacles. I tried a basic hyperlink from the directory in the database (which is MS access btw) but that didn't seem t ...Show All

• .NET Development Trying to send a mail via SMTP in VB 2005 - Authorization problem

  I am having a the same problem. I created a VB 2005 app that would try to deliver mail with both System.Web.Mail and System.Net.Mail. Both methods will work if I don't authenticate. If I use the fields property to authenticate through System.Web.Mail, I can authenticate and send to users of the outside world. If I use the Credentials property of the SmtpClient class, I can't authenticate. Here is some code. System.Web.Mail - Authentication works If the authentication code is commented out, the code can still send to anyone that has an email address on my domain but can't send outside of the domain. If I include the authentication code, it can send to either internal or external. ----------------- ...Show All

• SQL Server multiple connects to database

  How does reporting services handle connection strings. There is a single report using a shared datasource. Testing this report seems to generate multiple connections to the database for a single user. The report being tested has 4 datasets (3 to obtain parameter value lists) using the same shared datasource but the number of connections for the single user were 20 in one instance. When does reporting services make the connection and when does it release it It didnt seem to let these go when the report was done executing. Using RS2005 sp1 with DB2 The Report Server processes the dataset queries in parallel whenever possible. This is why you see three connections open when you run a report with multiple data ...Show All

  My SQL 2005 table has 7 exact redundant records. I opened it in a data sheet view and selected these rows and tried to delete them. No keys are defined and null values are allowed.
