• Visual Basic Using FileGet to read Array in Structure (VB.NET Express Beta2)

  I encounter a problem when using FileGet to read structure that includes an array. The code is: Public Structure Test Dim a() As Integer Public Sub ini() ReDim a(3) End Sub End Structure The following code use FileGet Dim i As Integer Dim te As New Test te.ini() FileGet(1, te, 1) i = te.a(0) The error message is: System.IndexOutOfRangeException was unhandled "Index was outside the bounds of the array." Does anyone know why Thanks. Jo   FileGet does treat arrays and arrays in structures differently - try defining your structure as: Publ ...Show All

• SQL Server SOAP API

  Is there any API available for getting assigned role information For eg: A user xyz has a browser role and other user zzz has a content manager role. Now, I should be able to pass the user credentials and get back the assigned roles. Thanks, No, such an API does not exist. The reason is that the "roles" that a user is assigned to depends on the item in which they are acting on. A given user might have "Content Manager" role on one item in the catalog, but not have any role on some other item in the catalog. In order to determine the roles in which different user groups are in for a particular item in the ca ...Show All

• Visual Basic PreparedStatement in VB6

  Is there a PreparedStatement in VB6 similar to Java Hi Shilpa, Yes there is. You will need to set the Command.Prepared property on the ADODB.Command object to True to achieve this. The Command.Prepared = True statement takes the CommandText and pre-compiles it, so it's actually a little slower than a direct SQL statement the first time that it runs, but every time after that, it will be faster.

• .NET Development Quick SQL question

  I am trying to build manually the UPDATE, INSERT and DELETE strings of my OdbcDataAdapter because the ones generated by the OdbcCommandBuilder are not going to be adequate. I will still be starting from the generated strings and build on them. To understand better what they do, I need to interpret a specific SQL predicate, and I am having trouble with an expression within. The following SQL command is supposed to ensure that a row in a table is deleted only if the data hasn't been changed (in OBDC style, parameters are designated by question marks): DELETE FROM MyTable WHERE ( (ColumnIndex = ) AND ( ( =1 AND TextColumn IS NULL) OR (TextColum ...Show All

• Visual C++ Dump files and obtaining stack information

  Hi All, Im trying to read a mini dump file using MiniDumpReadDumpStream, which successfully works, and want to know how to obtain stack information that is contained within this file. Ive found StackWalk64, which requires a handle to a process and thread to be passed in - how can this be obtained from the dump file If anyone has any examples - it would much be appreciated. Thanks AFAIK this is not possible. You can use VS or WinDbg to load the minidump file. It may be easier for you to create the stack trace as a seperate operation when you create the minidump. This is the way I do it. Al ...Show All

• Architecture Advantages of OOP ?

  Hello, Im a fun of OOP designs. I design my bussiness classes when I start a new project. Then maybe I will write mapper classes for bussiness classes to map DB tables or using an O/RM tool or an ODBMS . Think that this project is big one and it has long deadline. You will develop it 2 or 3 years. Requirements will be changed. To develop this project with OOP designs and n-Tier application design is good idea. But I am asking myself this question "Why am I choosing this long way ". I think the advantages of OOP are re-usable and flexible (when there is a new requirement). OOP makes less code behind user-interface. But I dont un ...Show All

• Visual FoxPro report preview form problem

  I posted a post related to some problem with memo fields in reports. What I've done so far was to create an intermediate table, a workbench with a single field of a character string length 95. When I need to preview or print a memo field I first format it and place every word sequentially in records of that table. It required a bit of coding but now it seems to work. In any event, the problem I am about to inquire is not related to it at all. It was just an introduction to show that I do have a preview form filled with some meaningful stuff to the limit. Here is the weird part: once I get this preview form with the report on it it cannot ...Show All
