• Visual C++ CDockBar::Insert

  There has been a huge bug in this MFC function for the last decade.  It shows up in applications that have many toolbars when you have some toolbars hidden and multiple rows of toolbars.  It mis-calculates the number of toolbars rows and drops you toolbar in some row below where you specify.  It's hugely annoying to the point of be unusable. It would be soooo easy to fix and it's very difficult to work around. What is it going to take for Ms to fix it    Pleeeeaaase, I'm begging here.  This is exactly where the bug is: CDockBar::Insert ... for (nPos = 0; nPos < m_arrBars.GetSize(); nPos++)  &nb ...Show All

• .NET Development How to dynamically change connection string in generated dataset class?

  I have a project with database classes which are generated from database objects. That is I add a dataset to the project and drag and drop a database object onto it. The problem with this is that I have to give a connectionstring which is stored in the code. This is ok while developing the application. But runtime I want to use another connectionstring, both for security reasons and because each user of the application will correspond to a database user (ms sql) and shall have a corresponding connectionstring. Is there an easy way to do this without having to restore to plain all datasets and do everything myself Of course you can. You ...Show All

• Visual Studio 2008 (Pre-release) DataContracts & svcutil & generated proxy oh my!!

  First off, I am still learning and this question may be way off because of my lack of knowledge of web services and WCF. I have a class and I am wanting to create a data contract. For example, I have my WCF service in one namespace and then I have a class in another namespace and I want to pass this class to a WCF method. My question is where does this class need to reside Should it be included in the same namespace as the service contract Does it need to be referenced in the .svc file And what effect does the svcutil have with data contracts, does it need to be part of the generated proxy Thanks in advanced for you help! ...Show All

• Windows Forms TabPages.Insert Bug?

  Is anyone else out there having problems inserting TabPages I thought it might be a problem in my main project, so I created a new WinForms test project, dropped a tabcontrol on the form, and added a line to insert a tab at position 0. Nothing else. My constructor looks like this: public Form1() {    InitializeComponent();     this .tabControl1.TabPages.Insert(0, "Test" ); }   But when I run I only get the two tabs the designer adds by default.  I've tried all kinds of other permutations and still nothing.  No errors, but no inserted tab either.

• Windows Forms Does anyone have links about Information Design & Layout for data-heavy apps?

  I'd like to check out some articles/tutorials/books/whatevers that discuss information & layout design. I'd prefer that the links are not too dependent on any programming language at all, though if the information is useful to you I'd like to check it out anyway. Share your links -- I'm very curious to read up on this subject. :) If your are looking some general reading on UI design I would recommend JoelOnSoftware: http://www.joelonsoftware.com/uibook/chapters/fog0000000057.html Max ...Show All

• Windows Forms Yes! Another DataGridViewComboBoxColumn Question!

  I'm sure everyone here is overjoyed!   Here's my problem. 1)I fire off a query and fill up a dataset, grab a datatable out of and bind it to a DataGridView object.  I'm not using any of the visual tools doing it all by hand. One of the columns in my dataset is an integer field called "status".  it has a value from 0-3. nothing fancy. I then fire off a second query and fill another datatable with textual values of what these statuses are.  examples: "low "priority" up to "high priority". with a range of 0 to 3 which corresponds to my integer value i have saved in my other table. I then create a DataGridV ...Show All

• SQL Server Use Command or BCP for large SQL statement

  I have an application (Java) which is converting a relatively large XML files (>8MB) and generating SQL Insert statements from the contents. The resultant SQL from the transformation is quite large (nearly 8MB also) and I'm just wondering if people would have an opinion as to whether to just place the SQL into a command and execute it or write it out to a file and use BCP or something similar. My preference would be to insert the data straight from the application to cut down on the number of "working parts" but I'm just worried there would be too many performance issues. For operational reasons I can't just pass the XML to S ...Show All

This is what my query looks like: SELECT a.account, e.account AS Expr1, COUNT(e.ord_status) AS SentOrders, MONTH(e.datetime_added) AS Month, YEAR(e.datetime_added) AS Year FROM executionreports AS e INNER JOIN accounts AS a ON e.account = a.account WHERE (e.ord_status = '0') GROUP BY a.account, e.account, MONTH(e.datetime_added), YEAR(e.datetime_added) ORDER BY Expr1 and the output looks like this: 1AA 1AA 328 4 2006 1CC 1CC 45 3 2006 1CD 1CD 8 4 2006 1MA 1MA 1167 3 2006 1MA 1MA 8 ...Show All
