• Windows Forms Throttling a Windows Form Application

  I have a Windows Form application that implements both BackgroundWorker and standard Threading. System.ComponentModel.BackgroundWorker System.Threading.Thread The BackgroundWorker objects are used to update the UI. The classes I made that run the long processing are threaded and have events that are raised as updates are made and when the threads complete. The BackgroundWorker sits and waits for these raised events, then updates the UI so the user can see the progress. All pretty straight forward stuff. I want to take this to the next level and implement processor throttling. Some of these actions can take many minutes, while potentially others could take hours. I want the machine to continue to be usable by other processes. The a ...Show All

• Smart Device Development MSMQ PPC win ce 4.2(Reader thread terminated)

  Have observed a strange behavoiur in MSMQ . Senario : Have two applications one on Pc and one on the PPC (WM5). which interact using MSMQ. sending and receiving of messages works fine when the ppc is online(or in network uses a wifi connection).

• Visual Studio Express Editions Publishing to install on offline computer

  I need to install my program on a computer that doesn't have the internet. When I went to publish it I changed the Install Mode to "The application is available offline as well" but when I went to install it, it tried to connect to the internet to install .NET Framework 2.0. So I checked the prerequisites and .NET Framework 2.0 was checked. I unchecked it but then when I went to install it, I got a message asking me which program to use to open the setup file. Anyone know what I can do Because ClickOnce is so ridiculously simple... it leaves out a great make things, one of which is including redistributable files, instead it uses a bootstrapper to try to install those files if they do not alread ...Show All

• Visual Basic VB and Outlook 2003 return items as mailitem

  I wrote and addin for outlook 2003 and whenever my program hits a returned email and I try to open it as a mailitem it crashes my program. What are returned emails if not a mailitem I can't seem to find a way to open those emails and parse them. Indeed what you are getting is a ReportItem ( http://msdn.microsoft.com/library/default.asp url=/library/en-us/vbaol11/html/olobjReportItem_HV05247366.asp ) I'm not sure whether this object is exposed in the Office 2003 PIA or whether you need to use it at all. If you don't need it or you don't care about the contents, you can easily skip over "unwanted" items by doing something like this: If TypeOf Item Is MailItem Then ' Do your processing ...Show All

• .NET Development Encrypting sections of Web.Config

  I have a websever running IIs 6.0 and the .Net 2.0 framework. I'm trying to encrypt sections of a web.config file on one of the websites that I host on this server. I have about 20 different websites each with their own IP address. From several MSDN docs and posts here and there I've learned that I can use the aspnet_regiis command to encrypt certain sections of my web.config. I'd like to encrypt the sections that contain passwords - such as the connectionStrings and the mailSettings. (I'm trying to implement the new Membership classes and the login control). My problem is that the documentation I have says a couple of things that I'm not sure how to do. 1. In one place in the MSDN doc ( http://msdn.microsoft.com/library/def ...Show All

• Windows Forms How to change font color on a rich text box on a child MDI form.

  I am trying to write a sample program for school. The program consist of creating a MDI application that when a user clicks the "New" button a child form is created. On this child form, it simply has a rich text box, so basically when you click "New" it makes something that looks like a blank NotePad file. The program is suppose to allow the user to change the Font Face, Size and Color of the active MDI form. I can successfully change the font face and the size, but I am unable to change the font color. I have a simple class file that generates the new child MDI form with the RichTextBox control. When the user clicks the "New" button, it runs the following code: frmTextPad myChildTextPad = ne ...Show All

• Windows Forms ConnectString in Debug and Release.

  In my Application settings I have a connectionstring setup to connect to a test database server. When I deploy a release, I update the connectionstring everytime to point to a production database server. I wonder is there a way you can set up both connectionstrings; when I change from debug to release in the Solution Configuration, it will pick up the correct connectionstring Thanks you so much!   Terrence When you debug the code the code run from debug folder and you should have app.exe.config which should have the connection string which points to debug server and under release there should be app.exe.config there you could use the production server connection string. Try it and see if it works. ...Show All

• SQL Server loading XML

  I am trying to load many XML files into SQL Server 2005 Standard Edition. Each XML file contains many individual XML items, each starting with: < xml version="1.0" encoding="UTF-8" > The files do not have a .xml extension. I do have a schema for the data. I can also get hold of a dtd file for the data. Since I am new both to XML and to databases I have been trying to follow examples wherever I can find them. I have not found the right example or tutorial. The closest that I found was in Kirk Haselden's book (a very nice book to learn from, by the way). On page 73 he sets up an OLE DB Source. His example works fine. But when I try to use XML Source instead of OLE DB as the source, I cannot get it to work. A typi ...Show All
