• .NET Development MFC and Managed C++ Web Service

  Hi all I need to develope a Web Service using C++ because some of the functionality to be added is code already done in C++ using MFC. I've been testing the Web Service with Managed C++ and I'm not been able to add MFC classes to the code. My question is: can MFC classes be added to Web Service (managed c++) If so, how can I add it And another question: can MFC classes be added to Web Service (ATL Server) If so, how can I add it Thank you very much in advance Vicent ...Show All

• SQL Server NULL values returned when reading values from a text file using Data Reader.

  I have a DTSX package which reads values from a fixed-length text file using a data reader and writes some of the column values from the file to an Oracle table. We have used this DTSX several times without incident but recently the process started inserting NULL values for some of the columns when there was a valid value in the source file. If we extract some of the rows from the source file into a smaller file (i.e 10 rows which incorrectly returned NULLs) and run them through the same package they write the correct values to the table, but running the complete file again results in the NULL values error. As well, if we rerun the same file multiple times the incidence of NULL values varies slightly and does not always seem to impact the ...Show All

• Software Development for Windows Vista How do I access Activity.Parent at design time?

  I would like to set the default values of a couple of properties on a custom activity, depending on what type of parent it has been dropped into at design-time (and possibly that parent's properties). What's the best way to do this I can't find a natural override in the custom designer, and it doesn't seem to make sense in a custom validator. If you look at the OnActivityChanged event, you can bind to e.Activity and from there you can get e.Activity.Parent and navigate the tree however you would like, eg: protected override void OnActivityChanged( ActivityChangedEventArgs e) { base .OnActivityChanged(e); Debug.WriteLine(e.Activity.Parent.Name); ...Show All

• SQL Server Report Layout - forcing absolute position

  Greetings, I have a report with all of the required data, but am having trouble with the positioning of the elements. The report has header-like, body and footer-like sections but I am forced [I think] into using only the body section of the report since SSRS won't let me put fields in the header/footer area (msg: fields cannot be used in headers or footers). btw - my report is always one page... never more. The center section (a table) may change in number of rows, but it will always fit on the page. So -- easiest way to ask this is: how can I lock the position of a field (or text box) to ensure it will always be in the same spot (acting like a header / footer) Thanks in advance. I ...Show All

• .NET Development Problem with c# and Access DB

  Hi, I got a strange problem, that doesn't accours all the time, it happens from time to time and that make it hard for me to debug it. The problem is that the application is looking for the DB on other location than it suppose to. In the connection string I defined only the name of the DB "Main.mdb", that define the application to search for the DB in the current location, but sometimes, it looks for it on the desktop. Any ideas Appreciate any suggestion. Jivago If you specify only the name of the database the application will look in the current directory for the database....sinnce you can not always tell what the current directory is...you should always specify the path to the database even if it is relativ ...Show All

• Visual Studio 2008 (Pre-release) UI layout the old way

  Hey I just started coding with WPF. I have an old project I would like to convert to .NET 3.0. But the new layout concept makes it a bit funny. I just want to place the buttons and textboxes as I would in .NET 2.0. But is there a way to get the layout to work as in 2.0. I don't like all the auto size and so on. I just need the old grid layout to place my controls where I want them and no more. Why would you want to do things the bad old way :-P I think you'll find it not that much harder to add auto-layout. Use a canvas instead of a grid. Or set HorizontalAlignment=Left, VerticalAlignment=Top on everything. ...Show All
