• .NET Development Recomended number of threads ?

  What is the max recomended number of running threads in an application(win app) What is the "limit" that above it, it will be better to use a thread pool Thanks Avi Threadpool is the good solution. if you don't want to use it... you can do some test with them and you'll see that you'll see the breakdown differs on every machine. what I can say to you...is not to abuse of threading. :) If you need more info about the reason to use Threadpool I can explain it . I hope this can help you. Dario ...Show All

• SQL Server ClusterDistance() of Zero for All Cases

  I recently added a nested table to a model that I had been using for a while. I noticed that after I added the nested table that the ClusterDistance() function returned 0 for every case. I went ahead and changed some of the keys for the nested table records so that the values would show up as missing and now the cases with a missing value have a non-zero ClusterDistance() value. Can anyone help me understand why this may be happening Thanks. How many clusters were in the model And what is the result of the Cluster() function for each case Can you post the cluster content (SELECT FLATTENED * FROM ModelName.CONTENT) Thanks -Jamie ...Show All

• SQL Server Calculated measures on Analysis server

  Hi, Is there anyway I can process calculated measures of the cube on server As of now its getting processed on client and its taking lot of client memory . We have got a good configuration server . Is there anyway I can configure to get this processing done on OLAP server Any help/tip will be appreciated Thanks, SP Just wanted to confirm that you weren't referring to cube processing time, rather than to query response time. With AS 2000, you can (to some extent) increase server-side query execution by changing connection string parameters: http://www.microsoft.com/technet/prodtechnol/sql/2000/maintain/ansvcspg.mspx >> Microsoft SQL Server 2000 Analysis Services Performance Gui ...Show All

• Visual C++ Linking static library to a managed dll

  I have a static library that i want to be able to link into a different project that is written in managed code. The project I am creating is a webservice and i need to be able to use the classes in the static library. When I build the project I get tons of link errors like unresolved external symbols.

• Windows Forms Dynamic selected Dataset and dispaly in DatagridView

  Hi Gurus, i have following problem. In my application I need a datagridview with dynamic columns. I created a dataset and I filled it with a SqlClient.SqlDataAdapter.Fill Method. After setting the datasource of my Datagridview the result will be displayed. But the problem - i like to display different columntypes (i.e.checkbox), but of course in my table were booleans displayed as 0 and 1 (how I stored them in the dataabase). Is (and how is) it possible to change the columntype in my example to checkbox.. Thanks in advance for your ideas. Stefan Solved ! ...Show All

• Visual Studio Express Editions Form.TomMost Property didn't work correctly on visual Basic 2005

  Hi every body in visual basic 2005 ,the form.TopMost Property didn't work correctly in visula basic 2005. I set TopMost property to ture,but my form lost focus when user clicks on another form. I Need this information to complete my job. I have a few items which are always on top (ObjectDock, for example), which sometimes disappear to the background. Usually I have to 'reset' it to be back on top. It doesn't use the .NET framework, so I guess the issue is that always on top is unreliable. I believe that there are probably some applications which use the always on top mechanism to bring a form to the foreground, which messes up forms which truly need to be always on top. I guess you can simply ...Show All

• Windows Forms Multiple Controls that have the same databind

  Two parts: Simple and Complex In your example, you are binding all of your comboboxes to the same bindingsource. Since the bindingsource wraps the currencymanager, you are telling it to keep all controls at the same position. You can get around this by creating multiple bindingsources, even if they have the same datasource. Tony ...Show All

• .NET Development How to get the max length of text field in a DataSet?

  I have a DataSet bound to an Access database. Is it possible to get the maximum length of a text field of a table in the DataSet Many fields in the database tables have maximum length values set in the design view in Access. When I examine the loaded DataSet in the VS 2005 debugger, I can't find any maximum length information anywhere in the DataSet or the "DataTable.Columns" objects. I wrote the schema of the DataTable to a file (using WriteXmlSchema) and I see that the XML schema does not contain maximum length information for any fields. I want the maximum length to validate user input on a form. Currently, if a user enters too much text for a field and trys to update the database, an exception is thrown stating: "T ...Show All

• Visual C++ VS .Net 2005, how to disable intellisense...

  Hi I am really frustrated with the performance of VS .Net 2005. This is because I always see at the bottom "updating intellisense..." and it uses 60% to 70% of CPU. How to disable this updating of intellisense... Please this is making Visual studio unusable. Thanks Chandra My guess is that Intellisense performance is killed by some of the following: excessive use of templates in code, #import for large native COM classes (biggie IMO), errors in parsing which cause loops (i.e. it never completes), corruptions in NCB files (deleting usually makes things better for a while),  preprocessor code greying, very large precompiled headers, slow update of class view pane.     I hav ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Model not showing up in game

  Hi all: I'm playing around with the XNA Framework more and starting to make sense of things. I've run through the 3D tutorial and I can see the p1_wedge model just fine. Unfortunately, when I try to make my own model and bring it into the tutorial, I don't see anything. I have a texture for the model as well as the .x file itself that I created in trueSpace 6.6, and I've verified that it compiles ok in the project. I don't get any runtime errors either. Maybe I've missed something in the documentation... is there a scale of measurement I should be using Are there guidelines for creating 3D models for use in XNA I'd love for that to be in the docs. Anyway, I've uploaded a couple of files to my website for reference: http://www.spel ...Show All
