  Hi, guys, I am trying to debug a project using visual C++ 6, which using some libraries in an SDK. I compile and run the demo in the SDK, there is no problems. But when I press F5 to debug and track, I cannot do it and assembly language appears; I cannot even enter InitInstance(). I open the stach, it is in SUMDLLAPI! 100f66e5(). I never meet such problems before. the libraries can be loaded and used; but cannot be debugged; I cannot observe the return values of any API in the lib. Thanks a lot.

• SQL Server Data of type SQLBIT always 1??

  Hello all, Apologies if this is posted in the wrong forum, however I wasn't exactly sure as to which one would be the best for my query... I have recently inherited the job of maintaining a database of internet logs and I am using the bcp utility to bulk insert rows into the database. The problem is that for the fields which are classified as SQLBIT in the .fmt file (and the field in  the database is bit) are always inserted as '1' even if the data is actually a '0'. Any value will be inserted into the database as a 1 except for NULL which is inserted as NULL. I tested changing the type to SQLCHAR in the .fmt file, and this allo ...Show All

• SQL Server SMO Connection String conversion

  Hi, I am using SMO in my application to retrieve data from SQL Server in order to display it in the UI (such as DB list, tables list, etc.). Eventually the user has a connection definition screen, in which he inserts his data. The thing is that in the background my application needs to use this data to connect via OLE DB. Is there a way to convert the connection string generated by SMO to an OLE DB connection string Thanks. Hi, sorry, AFAIK the conversion from sqlconnection to oleddconnection is not implemented by default, although they share a common interface, the IDBConnection. Perhaps you can bu ...Show All

• SQL Server OLAP cube design

  Hi, This is an OLAP cube design question. I have a cube that was running fairly ok but now has started showing memory errors as the data being processed has increased considerably, so I have started to doubt the design of the cube. I have an SQL database that stores the information of people visiting certain web pages of mine, and analysis server running on it so that I can do analysis of trends of people accessing my pages. For example, I want to know how many smokers(dimension : Smoker) from state Alaska(dimension : State) accesses page1(fact table data) of my application during 1st month of 2006(dimension : Acessing time) Now, the dimensi ...Show All

• Visual Basic VB.NET 2005 RC - Datagrid issue

  I have an application which uses a datagrid to display a property listing.   The list will contain around a quarter of a million records so I need the user to have a simple way to search. I have built a search routine which allows the user to type some text in to a toolstrip bar and then performs a search through the dataset.   The issue I have is when the routine finds a match, I need it to highlight the row on the datagrid.   This is where I have the problem; I cannot see how to achieve this.   I have tried searching everywhere (Google/Experts Exchange etc) and have seen some pretty ridiculous solutions such as mim ...Show All

• Windows Forms TextBox, decimal field and null values

  Hi all, As the username suggests, am new to all this- so appologies for what seems to be a silly question... Working on a small application on VS 2005, I've noticed that when binding a textbox to a table ('price') column of decimal value that accepts null values, whenever I erase the contents of the textbox, it gets 'locked' till I fill it back with a numerical value. In the "price" column's properties in the TableDataSet.xsd I've changed the dataType to string and changed NullValue to (empty), which ends with an FormatException thrown since the attempt to convert an empty string (Nothing or "") to decima ...Show All
