• Visual C# Need some help - very confused about arrays and custom classes...

  This is a bit of my code to create & populate an array of class Card (this is part of a larger Class Deck which is creating it's own little array of cards. public Card[] deck = new Card[25]; public Deck(int numPacks) { int deckCtr = 0; for (int steCtr = 1; steCtr < 4; steCtr++) { for (int fceCtr = 2; fceCtr < 15; fceCtr++) { if (!(fceCtr == 15 & (steCtr == 3 | steCtr == 4))) { deck[deckCtr].setCard(fceCtr, steCtr); } } } } The highlighted portion generates this error: "Object reference not set to an instance of an object". I'm sure I'm just not creating my array properly, I can create an single instance of class Card no prob ...Show All

• SQL Server Newbie MDX Question

  Let's say I'm doing a fairly standard MDX query: SELECT {[Measures].[Revenue], [Measures].[Expenses], [Measures].[Profit]} ON COLUMNS, [Products].[Name].Members ON ROWS FROM [My Cube] This will show the product name on the row axis, and several measures along the column axis. What if I also want to get the product ID (numeric key) in addition to the product name in my query. How would I do that I suspect that a cross join would work, but there is probably a much better way. I'm using ADOMD.NET to process the results. Might this product ID already be embedded in the returned CellSet object As I said: "Assuming that you have attribute ProductName with numeric key and text name column". It is n ...Show All

• Visual Studio Express Editions Setup and Deployment

  I have a program that I wrote using Visual Basic 2005 Express Edition, and I need to create self-extracting installer for. MSDN says to use the Setup and Deployment Template, but it is missing from the File-> Add-> New Project area where the rest of the templates are. I have been unable to download a template from Microsoft or anywhere else for that matter, what are my options The express system does have the ability to deploy programs, you need to use the clickonce methods. If you want to make a seperate msi installer you will have to purchase a third party product or one of the main stream Visual Studio Products. If you do want to use the click once system you can post your questions in the ...Show All

• Windows Forms Unable to move the position of custom control during design time

  Hi, I developed a WebCustomControl in c# 2003. Everything is fine but when I am trying to use this in VS2005 the control is not moving during design time. Actually it is locked.

  Hi, I need some advice on the data structures to use in C#. My need is to construct a something like a code syntax tree. what would the embedded data structures in C# to use so as to ensure memory optimisation and run time efficiency currently, stacks/lists/ dictionaries are my choice of options. If any experienced C# developer would give me some sound advice, I would like to hear from you. Thanks I am already using Lists. should I build my tree using breadth first or depth first approach the choice of a stack enables depth first but the pop and push portion is rather taxing on the efficiency performance. do you have any advice or recommendations ...Show All

  How in a script do you control whether the URL references will : - update the current page - use a fresh tab - reuse an existing tab - or open a fresh IE page Thanks Greg, To reduce the opportunity for malicious behavior (think pop-ups, pop-unders, etc.), this is not something that can be done via script. It's left entirely to the user's discretion. Hope this helps... -- Lance ...Show All

• SQL Server Deploying Reports in WSS 3.0 with more than one datasource

  Okay, now this is easy with standard report manager web pages using out of the box SSRS. But with WSS 3.0 integrated mode, it is not apparent to me. I have a report that uses a second datasource to drive a parameter choice. But when I look at the choices I have available to me in the Sharepoint document library for an .rdl file, it only allows one-to-one mapping to a datasource. So far my experience has been that without explicitly telling the .rdl report in the library to use a datasource, it does not just 'find it' as seems to be the case with the old Report manager application. I'm also experiencing some odd behavior in this CTP with parameter depth. Let's say I have a series of dependent parameters driving the report. So, we'll s ...Show All

• SQL Server PDF Rendering bug

  We are trying to publish a group of financial reports using SQL Server Reporting Services. We have hit a snag when we try to render the reports in PDF format. The leading spaces of each line are stripped in the output file. For example: Department 10.7240 - ICU Expenses SubDepartment -------- ------------- 1,200 100 454 150 Becomes: Department 10.7240 - ICU Expenses SubDepartment -------- ------------- 1,200 100 454 150 Does anyone know a solution for this problem By the way, we did upgrade to SP2. That did not correct the problem. Thanks for the information. Actually we are moving a fully formatted report from an old DEC Alpha system to .pdf ...Show All
