• Smart Device Development Signature to bitmap

  I am trying to convert a signature to a bitmap on a pda. I was using HoodCanalSystems control, but it isn't working on the new Palm Windows PDA and they are no longer in business. It returns a bunch of coordinates which it writes to a text file: 56,14,57,16 57,16,60,21 60,21,73,34 73,34,79,39 79,39,88,51 etc... I am using the following code: http://www.codeproject.com/netcf/Signature_Capture.asp Thanks, Aaron You have an exact url I looked for it and can't seem to find it.

• SQL Server Imrovenment MAX

  In my cube I have following calculation Max (([Dim Date].[Daily Date]. CurrentMember . lead (29) : [Dim Date].[Daily Date]. CurrentMember ) * [Hour24]. Children , [Sales]) but this calculation is very slow can I improve this calculation I have read this cool articale ( MDX Performance Hints ), but I don't understand how I can apply for my calculation. Thank you These recursive, moving window calculations are not easy to optimise. If you have any useful higher level in a hierarchy (maybe weeks ) you might be able to tune this calculation similar to tuning a YTD calculation. If you have time in your processing window another option would be to calculate a "Max 30 day ...Show All

• Visual C# How do I stop running a function?

  Hello, I need to know how I can stop running a function in the middle of running it. I cannot give any real coding examples but, I can get a structural example and show what I mean. private void TestFunc(string a, string b) { while(a != b) { try { // Code that should run like normal. } catch(Exception ex) { // If the code gets here I should stop the entire function right away! (TestFunc) } } } If the code gets to the catch I have to stop executing the function right away and run another function (which is handled elsewhere). This is a very newbie question but, I've not had to do this yet. Thanks for any help. Quilnux private void Test ...Show All

• Visual C++ Cannot convert type String^?

  Hello, I'm trying to do something that is actually very basic. I simply want to take a string and convert it to type int so that I may use it in my calculations. The code is: hours = int(lblpaycheck->Text); I apologize if its a completely obvious question, I originally learned to program in Visual Basic and I am currently a beginner in C++ and Java.

• SQL Server SqlServer Ev vs. MSDE Performance

  We have developed a mostly-disconnected smart client app written in C# that uses MSDE as a local backing store. With the announcement of SS Ev, we attempted a port of our app over to SS Ev. The port went smoothly, however, the performance has been significantly (very significantly) degraded. Before we being our investigation into the cause of the performance degradation, I thought I might see if anyone has suggestions on where we should look for possible performance issues. Any suggestions SQL Ev is not going to achieve the same performance as MSDE or SQL Express. SQL Ev has a downsized query processor (1.5MB footprint) and MSDE is a 40MB footprint with the functionality and optimizations to go with that. ...Show All

• Windows Forms Deploying a Protected executable

  Hi, I would like to use windows installer to deploy a protected .exe that uses a USB dongle. I run the protection software to create the protected .exe. I then copy the protected .exe into my Release directory, when I build the installer it will write over my protected version with the non-protected. I need the detected dependancies for this app to work right. So what I do is remove the project output from the installer and add the protected .exe. My installer than works fine, protected version is deployed. Question is, is this the correct way to do this Does anyone have a better way to deploy a protected .exe using windows installer Thanks Jeff Your protection software... is th ...Show All

• Software Development for Windows Vista Any MSFT website supporting CardSpace at all ?

  So I have Vista RTM running since more than a week now, however until now I haven't come across any MSFT (not to mention other corps) that are supporting CardSpace. How will MSFT try to convince people using this technology if they themselves not using it on RTM Or did I miss a site that does support it It is not something that as a whole, we can just turn everything on, and have support on our websites. It was necessary to ship the client (Windows CardSpace) before we could get adoption moving. While you don't see any sites right this moment, we have work going on all over the place, and as we proceed into the future, these websites will begin supporting CardSpace for authentication.
