.NET Development BinaryReader floats and carriage returns
How do you determine while reading floats from a file using binaryreader if you have reached the end of line(carriage return) Supposedly my binary file (.dat) contains a line of floats, then a line of strings. Before I can switch over and start reading singles I need to know where my line of floats end. I tried reading in the floats below and converting it to string in hopes that I would be able to pull out the "\r\n" or 10 13 carriage return values but it won't work. Any help would be much appreciated. private void button1_Click( object sender, EventArgs e) { String fileName fileName = @"C:\myfile.dat" ; FileStream fs = new FileStream (fileName, FileMode .Open); Binary ...Show All
Windows Forms Accessing variables in form from user control
Hello, How do you access variables that are declared in a form from a user control that is used in that form For example, I have a windows form A. A displays a user control B. When a button on B is pushed, I would like to decrement a variable that was declared in A. Thanks in advance! RC Brendan Grant wrote: You’ve got two main options for this... Either you pass in a reference (of your form’s type) to your form into your user control that can then access the variable (provided it’s publicly visible)... or you setup an event on your user control that is fired off when the button is checked and an event handler within your form’s code receives this event and there you decrement your value. ...Show All

Software Development for Windows Vista Vista SDK - will it include WZC header (wzcsapi.h) ??
I'm looking for a Vista SDK, but it sounds like I should wait for Vista Beta 2. The only reason I want the SDK is to see whether MS is publishing an API for Windows Zero Config (WZC) and whether it is the same as on WinXP SP2. For WinCE and WinXP these are called wzcsapi.dll and wzcsapi.h, though the API is not official for WinXP. Does anyone know about WZC in Vista Thanks. wzcapi.h and it's lib is XP only, on Vista and Longhorn (and XP SP2) you are supposed to use the native WiFi API's.

SQL Server Lack of vbscript support for SMO?
It is my understanding that Microsoft is abandoning support for vbscript by not giving it full SMO compatibility. Is that true Are my years of vbscript programming and all those scripts now a dead end What will Microsoft abandon next What do I tell my employer about his plans to migrate to Sql Server 2005 I guess I don't understand what you're doing with your VBScripts that makes things so complicated. I've found SQL 2005 very straightforward to maintain, and use SMO code to simplify repetitive tasks or to automate tasks to make my life easier as a DBA. ...Show All

Windows Forms Troubleshooting errors after a background worker operation
I have a simple Windows form with two buttons: - the first button calls a method that throws an exception - the second button runs a background worker whose RunWorkerCompleted event calls the same method that throws an exception My question is why the "Exception was unhandled" window displays in different places depending on whether the method was called via the background worker or not. Without the background worker, the error is displayed where the exception actually happens. When using the background worker, however, Visual Studio displays the error in Program.cs, pointing to the line: Application .Run( new TestApp ()); The latter behavior is not very helpful when debugging. It seems to me that both error wi ...Show All
Microsoft ISV Community Center Forums Protecting formulas in cells
Hello, Other than coding formulas, is there a way to protect a cell in an excel spreadsheet, no mater, if the sheet is protected or not, so that formulas can not be erased or overwritten Thanks Chrstdvd Well Andy, I mean that I have a macro that has code like this Range("H22") = "=Sum("A5:A16")". I had the idea to just make a macro that repopulates the cells with the formulas prior to the Save command. That would at least have the formulas ready for the next days work. I will not go into why or how the store managers erase them. Most of the time all I hear is: "The computer just did it". thanks Chrstdvd ...Show All
SQL Server Web Sync: strange behaviour with the snapshot size
Hi There's *strange* behaviour with snapshot size during subscription initialization. So... The initial snapshot has size about 9Mb at the publisher. After subscription creation, I notice that the subscriber downloads about 21 MB. It seems to me, that the snapshot is unpacked on the IIS, next, part of the files are packed again and just after it the changed snaphot is sent to the subscriber. Why How it can be solved It brings some extent nuisance... Thanks Paul Not only does subscriber apply the snapshot, it also has to check if changes were made between the time the snapshot was created and the time it was applied, and if so, apply/upload/download them as well. Maybe this is ...Show All
