• Visual C# FreeAllUnusedJunk() ? any such method?

  I've got a program that runs through a loop, and during this loop, consumes a lot of RAM. of course, .NET is smart, and auto-disposes.. so the RAM usage goes something like.. 40MB, 80MB, 115MB, 230MB, 307MB, then it drops back down to something small again. The thing is, when this loop is over with.. the process could be eating up 40MB RAM, or 300MB. Is there some kind of global method I can call that basically frees up ANYthing that's not in use Definitely will be different behavior. GC works really tight with free memory. It will start more often when free memory is really low. I suggest to test your code with FxCop, maybe will help you find some better cleanup solution. ...Show All

• .NET Development Slow Opening Initial Internet Connection in console application

  Hi, I have a console application which should read xml from the Internet at some point. I've noticed that it takes plenty of time (between 10-15 sec) for initially "setting" an Internet connection via the console application. The same code works instantly in a asp.net web project. The example below illustrates the problem: It takes 14 seconds for step 1 and 0,0 seconds for steps 2 and 3. All files on server are really small (about 1 kb each - 10-15 lines) using (System.Net.WebClient wc = new System.Net.WebClient()) { //step1 wc.DownloadFile("http://somedomain/test1.xml", @"C:\Test1.xml"); //step2 wc.DownloadFile("http://somedomain/test2.xml", @" ...Show All

• Visual FoxPro VFP6: Problem saving data

  Hi all The VFP database system is running in the server so that all the workstations can share it. The user complained that she could not save the data after amending. I tested to see whether I was able to save it on my side. It works successfully. I went back to the user’s workstation to verify it but still the same problem. I tried other workstations and found no problem so far. Assuming that there are a few possible causes: 1) Computer in the workstation is not maintained well. 2) Email virus will affect the database system if anti-virus software cannot detect it. 3) There is file caching problem in the workstation. The workstation will "hold" certain data and then release it to th ...Show All

• Visual Studio Express Editions Copy, Cut and Paste Functions in VS2005

  Hello-- I am trying to implement the copy, cut and paste functions in my program. However, it does not appear that Visual Studio 2005 supports getting the selected text by using the ActiveControl object like VB.NET 2003 did. Is there an easy way to copy the selected text of any control to the clipboard Thank you for your help, Dave Thanks for the response, but its not quite what I am looking for. I have several controls on a form, including a datagridview and some textboxes.

• Smart Device Development Differences between DotNet Compact Framework 1.0 RTM and 1.0 SP2

     Can anybody help me with the following problem I have been developing a Windows CE 4.2  Symbol handheld device which uses Scanner and RF hardware. The application is written in VB.NET and uses .NET CompactFramework Version 1.0 RTM (2002 - version 1.0.2268). It communicates with a Server Application via Tcp/Ip Sockets.

  Can anyone help me with a quick question I'm creating a Custom TextBox control, by setting up a control template. I want to use Converters and Validation Rules.

• Windows Forms MDI App: Multiple Excel files and Multiple WebBrowser controls

  I'm writing an MDI winforms app that displays multiple excel documents in multiple WebBrowser controls/child windows. If I open just one excel window at a time, interaction with the spreadsheet behaves normally. However, if I open a second excel window while one is already open, interaction with the spreadsheet in the first excel window transfers to the second window. For instance, if I click on a worksheet tab on the first window, it is removed from the the first window and displayed in the second. Or, if I start entering data in a cell on the first window, the cell doesn't enter edit mode but the formula bar in the second window shows the text i've entered. What I think is happening is that the second window takes the Excel Applica ...Show All

• Audio and Video Development IMFPMPHost help

  http://msdn2.microsoft.com/en-gb/library/ms698995.aspx HRESULT IMFPMPHost::CreateObjectByCLSID( REFCLSID clsid, IStream* pStream, REFIID riid, void ** ppv ); Question: I'd like to understand what this riid & ppv actually return. Supposedly, Media Source is outside PE and the created object is within PE. I don't understand how I can use the return value ppv. I'll infer from your question that you're trying to call this from your Media Source. Most commonly, a Media Source that wants to play protected content will call IMFPMPHost::CreateObjectFromCLSID to get its Input Trust Authority (ITA) instantiated in the mfpmp process. You're correct that (in general) this Media Source will be in the application p ...Show All

• Software Development for Windows Vista Windows DVD Maker won't work

  I have a Benq DW-1625 DVD-RW drive that is happy to burn Data DVD's within Vista. However, everytime I try to make a video DVD using Windows DVD Maker something goes wrong. It goes through all the encoding until it reaches 99.0% and the progress box says that it is finishing the disc. Then another dialog box opens up to say that "an error occurred" and that is the end of it. No DVD, a now useless DVD disc, and an hour and a half of my life wasted waiting for the bloody thing to encode. I have tried several times, each time changing some of the (very meagre) options available in DVD Maker, but always with the same result. I am using Vista build 5384 and any solutions will be great, I am getting so damn frustrated with this thin ...Show All

I have 100Mbit network between server and client computers Regards, Walter Also, the underlying transport protocol (most likely TCP/IP or Windows named pipes) is free to break of SQL Server network packets into smaller pieces. This means that when you're looking at network traffic you'll likely see packets in the size that the transport proto ...Show All
