• SQL Server Rows in Pages

  Hi everyone, I have a simple question about Rows in Pages for you. In my opinion, rows are the storage of the data in databases. I would like to ask that there are any important properties of Rows which I am not aware. Thanks If you could please reformulate your question a bit more specifically, it would be easier to answer ;) Anyhow, as a first note let me say that in SQL pages are the phisical units of storage, while rows can be considered as logical units. Say, when you perform a query and process results in application, you think of rows, while when you are TUNING the query, you think about disk accesses, that is, page read/writes. ...Show All

• Windows Forms datagrid column headers fire the click event

  VS 2003 I have a datagrid, and on the click event I process the selected row. You click the selector on the left side of the row. If you click any of the column headings, the click event fires for the row that currently has the focus. So if you are just trying to drag and re-size columns, it fires and process that row. I just want my code to execute if you click on the record selector to the left. How can this be done Thanks lol :-) yes :-P I love doing this stuff, helping out you guys succeed and making sure you get the best experience possible! Besides, I want to brush up my skills and show them off (if I do have any!) ;-) ...Show All

• Visual Studio Tools for Office GetObject and Createobject fails with Outlook 2007 RTM

  Hi, I have a VB.NET application (.net2.0). Running on Vista RTM with Visual Studio 2005 I have an application that used to do a GetObject(Class:= "Outlook.Application" ) and it always worked until I upgraded to Vista and office 2007. Now this used to work under XP Pro and Office 2007 BTR. Now all of a sudden I am getting the following error, and I cannot figure out why. --> System.Exception: Cannot create ActiveX component Any idea what I can do to get this going again Thanks, Ryk Hi Ryk The better place to ask this would be the Outlook programming newsgroup, especially as you're not using VSTO: http://msdn.microsoft.com/newsgroups/default.aspx dg=microsoft.publ ...Show All

• SQL Server Newb question

  If I am using Ado.Net from a .Net Class library hosted outside SqlServer to do Sends and Receives do I have to use anything else other than queues The reason I am asking is because I already have an abstraction layer for a couple of our queueing systems and I was hoping to put SSB in there as well but the abstraction layers' primitive is the Queue not Conversation/Dialog/Service, etc. Thanks Costas Dialog conversations are persistent sessions between two services -- the initiator and the target service. When beginning a dialog, you must specify the initiator service in the from argument and the target service in the to argument. Even if you use dialogs for one-way messaging, you still need a 'from' servic ...Show All

• Visual C++ Simulating Left Mouse Button Click

  Hi, At the moment, I am running into a problem which is this: Every time I right-click on a TreeView item in my application, the selected item remains the item prior to right-clicking rather than changing to the right-clicked item. While this isn't exactly a BUG, it is quite an inconvenience. The most obvious solution to the problem, to me, is to simulate a left-button click in the right-click NM_RCLICK event that will in turn select the item prior to any further actions. Is there a better way to accomplish this If not, how can the left-click simulation be accomplished Thanks in advanced. ---Dan To simulate mouse clicks, you can use mouse_event and SendInput. However, I think it will be better to use ...Show All

• Software Development for Windows Vista Truly Dynamic Runtime Activity Property Nirvana

  I'd like to acheive "Truly Dynamic Runtime Activity Property Nirvana". My most critical custom workflow activity needs to expose a list of items that is not known at custom activity compile time. Each item in the list can be bound to from other activities - this is a pretty powerful concept for our workflow application that makes it very useful for end users that design their own workflows with my custom activity. I've figured out a solution where this dynamic custom activity is possible but it involves dynamically generating / compiling a brand new custom activity class on the fly - not the prettiest solution and I'm trying to create a better solution. Ghenadie has a neat example of how to create dynamic properties here ...Show All

• Internet Explorer Development opening new tab in IE7 via IHTMLWindow2::open method. Possible?

  hi i need to open new tab in IE7 from my extension code and to get an IHTMLWindow2*, pointing to this tab. Exactly tab, not a new window. Is it possible to do it via IHTMLWindow2::open method or are where any other ways to do it from extension I walked through some docs and forums and heard opinions that a place(new window or tab) in which IE7 opens pop-ups (as ones created by IHTMLWindow2::open) is controlled by user settings and extension can't change it Can't anyone tell is it so So sad if it is....

• Visual C++ Help button get chm instead of hlp

  I have a application built around a CPropertySheet derived class. The help button is looking for 'app.hlp' file (this is the default MFC stuff, I've not added anything other than moving the button). How do I get it to look for a 'app.chm' file instead I've tried the following using a test help file in InitInstance() //First free the string allocated by MFC at CWinApp startup. //The string is allocated before InitInstance is called. free((void*)m_pszHelpFilePath); //Change the name of the .HLP file. //The CWinApp destructor will free the memory. m_pszHelpFilePath=_tcsdup(_T("C:\\filezilla\\filezilla.chm"));     EnableHtmlHelp(); but i just get "Failed to launch help" You need to ca ...Show All

• Community Chat I can't believe most Windows users don't know how to use toolbars, OMG.

  This is most irritating. Almost all of Windows users in my company don't know how toolbar works. They don't know they can enable toolbar, take out toolbar, customize toolbar, and not even the simplest of all, move toolbar around. Toolbar is so simple, standard, and flexible. And yet, they don't know how to use it. And now, I think that's the main reason why IE7 doesn't support moveable toolbar, and that pisses me off even more. Argh. Quite true, Hans. (this subject is a pet-peeve of mine, so I'm going to interject a few retorts... ): Users do not want or need to configure such things. Users want things to stay the same. Users don't actually mind learning how to do something as long as it ...Show All
