• .NET Development Event And Threading.

  I was just doing some code, when i noticed 1 thing. Lets take this example. We have 2 objects. object1 have a worker thread, and an event. object2 subscribes to the event, that object 1 exposes. object1's worker thread calculates some stuff, and when its done, it raises event, and object2 catches it. Heres the problem. The method thata object2 got, to handle this event, runs in the SAME thread, as the thread that it was raised from(This is an issue when it comes to win forms). When i find this thing that i wonder about in OO things, i try and take the context, into some IRL example. I have tried over and over again, but this makes no sense t ...Show All

C# 2.0 I generate the report and all is OK but when the user try to print (print button in toolbar), the application open the printdialog, I select the printer and press Ok.

• Windows Forms Problems with MIME settings at the hosting provider

  Hi, My web hosting company is www.brinkster.com and I have asked them to enable MIME type for ".application". After a short period of time, the extension was not recognized anymore (404 Page not found) so I have asked them to reenable the settings. This is what I have received from their suport: ------------------------------- Hello, I am not sure what has happened now but I have just reset the MIME settings for the ".application" extension.  It is possible that this extension name is too long for our server to recognize it.  If problems occur in the future, would it be possible to shorten the extension name (for example to ".app ...Show All

• .NET Development filling of dataset takes incredibly long time in Visual Studio 2005 RC

  I am working in Visual Studio RC 2005. I am filling a dataset by calling a stored procedure. As long as the amount of data that the stored procedure returns is small, everything works fine. However, for larger, but still rather small amounts of data (getXml() on the dataset returns less than 25kB), the filling takes very long time, sometimes even timing out. Even worse, the sql server is brought to a complete standstill working at almost 100%!! It doesn't really seem to be connected to the filling of the dataset either. I first observed the problem when I tried to call ExportToDisk on a ReportDocument (crystal reports) which t ...Show All

• SQL Server GetValue on a DTSProperty Object

  In an Integration Services scrip ttask, I am trying to get the value from a DTSProperty of a Connection Manager object. The code seems like it would be very straight-forward. Here is what I have... Dim oCM As ConnectionManager Dim oProp As DtsProperty Dim sValue As String oCM = Dts.Connections( "SomeConnectionManager" ) oProp = oCM.Properties( "ServerName" ) If oProp.Get Then sValue = oProp.GetValue() End If The line inside the If block is the problem. Once you have a DTSProperty object, you should be able to get to the value of that property. GetValue is a method that either I can't ...Show All

• SQL Server SQL SERVER 2005 REPLICATION (SNAPSHOT GENERATION FAILING)

• Visual C++ Low-level Threading

  My most basic threading implementations don't seem to update nearly as quickly as they should. The program below seems to get stuck on the Sleep() call for a fifth of a second every time, even though I'm requesting a Sleep of a fiftieth of that. If I remove that call, the thread takes over the CPU, as expected. I understand that Sleeps are inaccurate but my previous experience has shown it to be off by a few milliseconds, not a few tenths. long t = 0; DWORD WINAPI run(LPVOID param) { while(true) { printf("%f\n", ((float) clock() - t) / (float) CLK_TCK); t = clock(); Sleep((DWORD) 1); } ...Show All

• Windows Forms Webbrowser Control Memory Management Question

  I have a C# application that uses the webbrowser control. I've noticed that as I load more web pages through the webbrowser control my program continues to consume more and more memory. (It starts at 9MB and quickly climbs to 40MB by simply loading web pages.) My question is really two part: Q1: What is the reason for this compounding memory comsumption Web cache, memory leak, ... Q2: Is there some sort of garbage collection I should be manually performing such as routinely clearing some sort of web cache in RAM   JBrown9264 wrote: But I am still left with the problem of memory consumption.

• Visual C# SQL Server 2005 and Threads - Licensing

  I am working on a project that will require the use of SQL Server 2005 Workgroup Edition. We were planning to use the version that comes with 5 CALs instead of the version licensed based on processors due to the enormous cost difference. Our customer who will be using this is a goverment agency and MS charges them ~$800 for the 5 user version, but the version licensed by processor is ~$20000. This software will be potentially installed in lots of locations so cost is a big factor. The application I am working on is using c#. I am being told that if I use threads, each t ...Show All

• Smart Device Development Debugging and deployment problems on WM5.0

  Hello I have a couple of questions I can't figure out on my own. I've written a program that runs fine when I use the PocketPc 2003 emulator. It also builds for smartphone 2003 and both smartphone/pocketpc WM5.0. The problem is that it doesn't run on other emulators than the pocketpc2003.
