• Visual Basic Run-time error '-2147467259 (800004005)'.... HELP please!!!

  I created a simple database program using VB 6. I use ADO connection. Though, I used DAO too for my DBGrid. I also use classes and modules. I was able to run and compile this program. I actually was using it for three months now. Then, i suddenly encountered this error: "Run-time error '-2147467259 (800004005)': Unrecognized database format:'<my .mdb path>'". I tried searching Microsoft KB but found none. I searched even the whole Microsoft site but to no avail. The only thing i remember before i encountered this is a MS patch was installed in my PC. The installation is automated by our company's servers. When i checked the last patch being installed before i encountered the error, MS06-034, it's a patch for ASPs which i ...Show All

• .NET Development build query based on user input criteria (search function)

  I have a search form which contains a set of search criteria and a datagridview. the datagridview is populated by entering none or some of or all of these critera and click on "search" button. the search criteria are: name, dob, gender, date_time_registered, active , etc. I am able to build a simple query for each possibility, e.g. only search for one field, or search for all fields, or search for any 2 or these fields. This is rather inefficient. Is there a way to build one query to accommodate all possibilities I tried to do something like this: SELECT * FROM patient WHERE name = AND dob = AND date_time_registered = AND active = assume user only specified two criteria: name and active, I did this in my code ...Show All

• Software Development for Windows Vista Are your customers able to modify workflows?

  Hello, We are considering use of Workflow for internal projects with not well defined or ever changing business rules. I believe implementation time (and especially maintenance) for such projects can be improved with WF. However, it is crucial for us to know that we can build a framework where not only developers but people from other departments (support workers, business developers and even customers) can take care of some workflow scenarios. If it's still us who will have to build and maintain all scenarios, then we need to perform a comprehensive analysis of where WF gives us benefits in comparison with traditional .NET components. In case you have a great experience with WF in your organization, can you please say a couple of wo ...Show All

• Visual Studio checkout a file.(VSS+c#)

  Hi. I connected to VSS using COM objects, that is located on the server. When I checkout a file to C:\test it checks out to the server c:\test and not to my local PC. IS there away to checkout not to the server's local computer folder but to the local computer from where the appiaction is run. Since not all users has access to the server machine. I am tring to find the local path's PC (user loged-in) when accesing the server.. (I use impersonation) Thank you in advance. I understand it is a server-side code.. But because it is, you saying what I am tring to do is impossible.. could you explain what exactly you mean "Because ASP.net is server-side code". sorry for aski ...Show All

• SQL Server CSV file as a data source

  Hi, Can a CSV file be used as a data source for Microsoft Analysis Services 2005 Rgds hari You can create SSIS pipeline, which will read CSV's and then uses AS Processing Task to load data into partitions. I have done it in the past, and while it is not a smooth ride (especially when your partitioning scheme of the cube is not trivial), it can be made work. ...Show All

• SQL Server SQL Server 2000: VB Client: (250,000 login + logouts per hour) OR (1500 Active Connections)?

  I understand that it depends on what we do. Here is the use case: Number of simultaneous users (systems): 800 Each System needs (max) 4 connections Environment: Windows 2003 EE , SQL Server 2000 EE, Two Tier VB Client Apps with good hardware (quad dual code with 32 GB RAM). And connection is being opened before executing an SP / SQL Statement and will be closed immediately (ADODB.Connection.Close + ADODB.Connection = Nothing). And most of these SP / SQL take few milliseconds (or lessthan a second) and gap between calls, 50% of the times, will be few seconds. And at any give point of time Average Number User Connections = 200 to 500 From server side, we are seeing around 250,000 login + logouts (Audit Login + Audit Logout) ...Show All

• Visual Studio Team System Ridiculous code coverage results?

  We're getting interesting code coverage results from unit tests. In every class that implements IList<T> and therefore must implement System.Collections.IEnumerable.GetEnumerator(), the code coverage result for GetEnumerator is absurd. These methods are 12 lines long, but code coverage says that 2400 or so lines aren't executed. The results roll up to the class level and then the namespace level, and really skew our results. I fully believe the methods are never exercised, but the coverage counter should be able to figure out how many lines there really are in the source. In addition, when coverage coloring is used in the IDE text editor, files containing GetEnumerator methods are painted randomly, as if the painter is computing a ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Draw without Texture

  do i HAVE to use a Texture/Texture2D/Texture3D loaded from a file to render anything within XNA, or can i give a buffer to a SpriteBatch or even tell it to just draw a simple line thankyou SpriteBatch can only draw textures, but if you write your own code that calls DrawUserPrimitives on the graphics device, you can draw any kind of geometry you like. You will probably want to set a BasicEffect, which has a property indicating whether it should draw textured or not. ...Show All

• Visual Studio Express Editions Simulate hotkey press

  Hi all, I'm trying to simulate some hotkeys to activate a program (though MapVirtualKey in use with keybd_event didn't work). I also tried simple SendMessages and PostMessages, but they didn't work eather (neather did the Screen Keyboard from Microsoft). As I kinda gave up the SendMessage to the Program itself (Send a mouseclick to a specific window on specific coordinate)... I need to simulate the hotkey which is set in the program... I already tried: keybd_event(VK_NUMPAD1, MapVirtualKey(VK_NUMPAD1, 0), 0, 0) keybd_event(VK_NUMPAD1, MapVirtualKey(VK_NUMPAD1, 0), KEYEVENTF_KEYUP, 0) But that didnt work...
