• Visual Studio Express Editions Disabling the close button

  This may have been asked before, but I cannot get a solution to this - how to disable the close button in the title bar (the red cross on the upper right corner). I have seen code examples in the net using the API functions which are supposed to work in VB6, but they dont in my Express Edition. You can try this to hide the x button. On the properties of the form1 for example look at properties and find controlbox and than set it to false. It will hide the x button but your app can be closed than by pressing ALT+F4 Hope this helps. ...Show All

• Visual C# How to assign 4 bytes of float to byte array

  I need to assign each of the four bytes of a float type variable to four bytes of a byte array. Can someone suggest a way to do this In essence I would like to do this: byte_array[0] = float_byte1 byte_array[1] = float_byte2 byte_array[2] = float_byte3 byte_array[3] = float_byte4   This array will be sent via a USB transaction. On the other end I will need to re-assemble the float type variable... In C++: byte byte_array[4]; float f = /*something*/; memcpy( byte_array, &f, sizeof (f) );   ...Show All

• SQL Server Value "+00000000000000" considered as NULL values in the last column

  Hello I use a Flat File Connection Manager for a file with 18 columns. My column delimiter is the "~" caracter and my row delimiter is "{CR}{LF}" The source files contains about 2300 lines. None of them contain NULL values. My last row is a numeric(16,2). Even if it is not the appropriate type for the value I want extract, it works with all my columns. My problem is with the last column. I have read the SQL Server 2005 interpretation of the row delimiter as actually the last row column delimiter. But, here, my values are OK and put in the destination table if it is not 0 : "+0000000001352" ...Show All

• Windows Forms CLickOnce with Tomcat

  Our requirement is to use Tomcat as Web Server and I am exploring possibility of deploying our smart client using ClickOnce. Is it possible to use ClickOnce with Non-IIS web Server, specifically Tomcat. If so, what do I need to do. Any changes required on tomcat side to support this I would appreciate any ideas on this. Thanks, Sushma Hi, ClickOnce does work with non IIS web server. You just need to have the MIME types on the server configured correctly for the web server to server .application files.

• Visual Studio Express Editions 2 events at once

  I'm creating a simple, old, black and white tennis game for practice. I've created an event handler for 9 keys - 2 for moving 2 paddles up, 2 for moving them down, 2 for left and 2 for right. I also have an Enter key that starts the ball moving. The problem is that when I press Enter, none of my other keys work, until the ball goes off the screen. Does anyone have any suggestions how to fix this If you provide mode detail, someone might be able to provide some guidance. I'll assume this is a WinForms application. What event are you subscribing to to handle the keys, KeyDown, KeyUp, or KeyPress What is the c ...Show All

• SQL Server Bulk Insert -- Access denied issues - 2

  Hi All Same situation as described here , same issue. SQL Server(SQL2005 on Windows2003) uses domain account. This domain account enabled to be trusted for delegation.

• Visual C# Future C# string optimization directions

  This is a topic of academic interest to me.  Are there any plans to optimize code patterns such as: string results = ...; bool foundSomething = results.ToLower().Contains( "something" ) ) Here, I'm making a case-insensitive search and it seems that ToLower() is an unnecessary use of CPU cycles and memory accesses.  One possible solution, which isn't very extensible, is for ToLower() to do a lazy-copy: it will first make a reference to the input string and add a "use-lower-case" bit.  Contains() uses this bit to do the case-insensitive compare on the original string.  Brian ...Show All

• Visual C++ Writing a Music Player that supports MIDI Instruments

  I want to write a Music Player that can play MusicXML files. These have information about them that can be used for conversion into MIDI, such as what instrument each part should use. However, in conversion to MIDI lots of information is lost, like crescendoes,diminuendoes, and emphases. I want to write a Music Player that can play these files, keeping this information in, but use the MIDI instruments. Is this possible, andd can anyone give me any pointers, as I don't really have a clue where to start.

• Game Technologies: DirectX, XNA, XACT, etc. Rotation matrix: absolute rotation instead of relative?

  Hi, When multiplying rotation matrices for rotating around x, y and z-axes R = Rx * Ry * Rz ( http://en.wikipedia.org/wiki/Rotation_matrix ), I get a relative rotation matrix, meaning that rotation around Y is not the original Y-axis, but the new axis that has "occured" after rotating around X. What I want to do, is to have absolute rotation, so that the Y-rotation is performed around the original Y-axis, and not the new one (absolute rotations instead of relative). If you know the math for this, I would appreciate if you let me in on it :-) Thanks!! > I get a relative rotation matr ...Show All
