• .NET Development Accessing via OleDB with an ODBC driver

  It could happen that you have to access a Database striclty via OleDB way For example to gather the schemas information in a standard-unique way with the GetOleDbSchemaTable, instead of the Database dependent GetSchema of the generic "Connection" classes If you have only ODBC driver and you weren't succesful in finding a working OleDB connector, you can try with the MSDATASHAPE oledb connector.   I needed to access a MySql database via OleDB (to gather schemas infos like if I used OleDB generic provider) but i didn't found a working OleDB connector, so i installed the MySQL ODBC 3.51 Driver and found succesful the following:  OleDbConnection oconn= new OleDbConnection (" Provider=MSDATASHAPE ...Show All

• Architecture Design processes for commutability?? MCSD.NET Book

  Hi Forum I'm currently reading the book "Analyzing Requirements and Defining Microsoft.Net Solution Architectures" for the 70-300 exam. I have come across a section where best practices for designing for scalablity is listed. They explain Commutability and come with an example. The problem is that I do not see the benifit of the solution they suggest. The section states the following: Design processes for commutability Two or more operations are called commutative if they can execute in any order and still obtain the same result. Typically, operations that do not involve transactions are commutative. For example, a busy e-commerce site that continuously updates the inventory of its products might experience content ...Show All

• Visual Basic Groupbox Issue

  Got a question How do you overlay a groupbox without associating it with the one thats under it I have got a few groupboxes and I would like to stack them on top of each other(I am using them for different things within my main form). I can slide it to the side and I can change the visible property just fine and it shows, but when I put it on top of another groupbox, I can only get it to show when I change the visible property on the first groupbox. Or Is There a Better Way Davids Learning This is happenning because of the designer...when you drag a control ontop of the groupbox the gesigner wants to make it a child control of the control (groupbox) that you are placing it on top of...The wo ...Show All

• Visual C# adding permissions to a file

  I have a program that uploads and downloads an excel file to the server. Works great except for 1 snag. Every time a new file gets uploaded the file permissions don't allow me to download it again. The file needs to add the permissions for Internet Guest Account (SERVER\IUSR_SERVER)) and to allow all. The only parameter I have is the file location and file name on the server. I know its possible but I'm hoping to get a fairly simple solution to it... I don't suppose there is a method changePermissionsOnNTFSFile(string file_location, string account_name, string input_access) Thanks. Hello Michael, thanks for the reply. I'm still having difficulty because I'm brand spanking new to the whole c# s ...Show All

• Windows Forms ClickOnce exprired certificate fixed...not.

  Hi All, I've had a look at http://support.microsoft.com/Default.aspx kbid=925521 for the "solution" to expired ClickOnce certificates, and I can't get it to work. I've followed the instructions carefully, and went to compile, and it failed with 13 errors, heres the first one: Error 1 error LNK2019: unresolved external symbol __imp__CryptMemAlloc@4 referenced in function "void __cdecl ReadPFXFile(wchar_t const *,struct _CRYPTOAPI_BLOB *)" ( ReadPFXFile@@YAXPB_WPAU_CRYPTOAPI_BLOB@@@Z) RenewCert.obj I'm not a C++ programmer, so I've no idea what this means.

• Internet Explorer Development IE7 FAVICONS or desktop icons NEED to separate discussion between IE shortcuts or Faviacons or desktop icons as folder links

  I just installed Internet Explorer 7 today, which I guess is a.k.a. Windows Live . All of my fancy customized shortcuts on the desktop disappeared and each got replaced by the same generic windows icon. Right-clicking & changing the icons in properties no longer works. Also, when I create an internet shortcut while browsing, that creates a shortcut with that same generic icon (not even an explorer logo). Now my desktop is just one forest of identical icons. Anyone know how I can fix this I've wasted all day without success. I like the features I've seen, but the loss of the icon control is not something I can tolerate. I will commence the uninstall as soon as I send this. ...Show All
