• Visual Studio "Get Latest Version (recursive)" gives list of files for each project

  Hi All, We are trying to implement MS-SCC API functions (v1.3) for a SCM. When a solution is opened in VS2003/VS2005 with multiple projects and choose option "Get Latest Version (recursive)" for a solution, SccGet() function is called with list of file for each project. I want to show list of all files in a dialog box. While if "Get Latest Version (recursive)" is selected for a project, it shows all files (including files from directory).

• SQL Server Problem running DTS package from Dot Net

• Game Technologies: DirectX, XNA, XACT, etc. Starting work on my GUI system

  Well, I've hit a wall with my game's development, and since there was no GUI with XNA 1.0, I've decided to go ahead and make my own GUI system. I implemented a lot of mechanics for my game, but I need greater interaction to proceed development in a sane manner. So far I've just implemented the text drawing stuff from scratch. It uses only monospace fonts generated with BMFontGenerator without using the generated .xml file. It's decidedly minimal to use only monospace fonts, but keep in mind two things - 1) my particular game doesn't require anything more robust than monospace fonts and 2) a game's engine should be designed around the game's specifc requirements. Otherwise you're scope creepin. I remind myself constantly not to let cool ...Show All

• SQL Server datetime to date

  Hi, everybody. I have a parameter from datetime type. Its' values are stored with date and time values together in the database. But I only want to show its' date value to the user. How can I do this If you are using the datetime values as a parameter, the easiest way to do this is to create or modify your parameter query: add a column with only the date value of the other datetime values. SELECT Date AS DBDate, CONVERT(VARCHAR(10), Date, 101) AS ViewDate FROM <<Table>> This query shows also the date in the format mm/dd/yyyy . Then use this query for the parameter: use the DBDate as Value and the ViewDate as label. ...Show All

• Visual Basic Date and Time Format Problem

  Question one May i know is there any time picker in VB.NET 2005 which allows user to enter a time The DateTimePicker can only retrieve current time and i think of using few combo boxes to form the format like hour,sec and AM or PM. Apart from that, is there any other way of doing it If i use the combo boxes method, how to parse the concatenation string as time and store in database   Question two I allowed user to select a date from DateTimePicker and format the date as the below and store it in database.   FormatDateTime(join_date.Text, DateFormat.ShortDate)   The datatype of that column i set it to string in order to prevent any format error. One problem is that the time format (DD/MM/YY) appea ...Show All

• SQL Server multivalue parameters - is this possible ??

  i am trying to build a report that uses multivalue parameters - the report is a simple listing report that lists out a list of cases as a table - the data is obtained from a view which just returns all details for all cases there is no user input for the selection details - am going to be calling the report and passing over the parameter values directly to it. there are several parameters for the report - they all default to "All" for each of these parameters, i need to be able to either use the default value of "ALL" or to enter a list (comma separated ) q1) could i just enter the list as a string comma separated list (rather than as multivalued parameters) and then use this list to filter the data usin ...Show All

• Visual Studio Express Editions Use of RegistryKey

  I have been looking in the forums for info on RegistryKey and found lots of good info on read/creating/deleting/etc. My question is very basic...Can I use Registry Keys to store flags that one program sets and another reads (at some subsequent time). I basically want to know if a user interface program has set a flag that other programs read and execute some functions based on it. Note that these are not programs running simulataineously, but will query this flag later on. Thnx Well what do you know! ! ! I did use My.Computer.Registry and there is a trick You just can’t put data init. You have to use the CreateSubKey Method. Also please note that this Board’s editor wraps line irresp ...Show All
