.NET Development Spontaneous Uninstalls
Hi: This is a bit wierd...we have a number of .net applications (2003) that use crystal reports. Recently (and very intermittenly), some of the applications will be in use and they will spontaneously uninstall themselves. We reinstall and they run fine...no errors thrown. My search on the internet hasn't turned anything up and I was curious if anyone had any thoughts. Thanks! f_red Thoughts... I'm thinking is is going to take some social engineering. .NET apps just don't do this out of the box; if you'd want them to, you'd have to write some pretty complicated code. Anybody out there that is adverse to the idea that .NET is getting main stream Who has access Any Click-Once deployments (poorly understand by me and anybody I k ...Show All
Gadgets Possiable to have text with no background or transparent background
I'd like to have text just floating with no background at all how would I do that. Thanks I have this working <body> <g:background id="bodyBackground" src="blank.png"/> <script language="JavaScript"> text = "Some text"; bodyText = bodyBackground.addTextObject(text, "Segoe UI", 12, "White", 1, 1); </script> </body> the style tag seem to make the text dissapear If I load a non blank png, the picture is offset to the right by quite a bit, therefore you can't see anything, plus you get a weired halo floating away from the main part of the picture and the text. If I scale up the font size of the text I ge ...Show All
Smart Device Development Type.GetConstructors() - InvalidProgramException on CF, works fine on the standard framework
I have a piece of generated code that the CF (2.0SP1, August patch) just won't accept. The code is working just fine on the big framework, but mscorlib in CF gives me an InvalidProgramException. The context of the call to Type.GetConstructors(): protected virtual object CreateInstanceWrapper(Type type, params object[] args) { object instance; #if !CF instance = Activator.CreateInstance( type, args ); #else ConstructorInfo constructor; Type[] argTypes; argTypes = GetTypeArray(args); constructor = type.GetConstructor(argTypes); if (constructor == null) throw new ArgumentException("There is no matching constructor"); instance = Activator.CreateInstance(type); constructor. ...Show All

Visual Basic WebBrowser control in vb.net.
Hi, How can a get the text from WebBrowser control in vb.net. Thread will be moved to the appropriate forum once the forums are back up and running again. You can use the DocumentText property: Dim theHtmlText as String = Me.theWebBrowserControl.DocumentText or you can go into the Document property itself, there you can go into say the Body property to get the body part of the Html page.

SQL Server The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel
I'm using SQL Server 2005 (SP1) Reporting Services on Windows Server 2003 SP1. I access the report server from Internet using SSL, but the server is not exposed directly to the internet. It is behind a firewall, where the required ssl port is setup and is working fine. In my Reporting Server, the /ReportServer folder works perfect and I can navigate and view all reports. It is the /Reports folder the one that does not work fine. I can enter the /Reports folder, and can list all the reports. But, when I select one of the reports, and it starts rendering, I get the error message: "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

Visual C++ dataReceived String???
I am receiving data from the serialPort. The data is in the form of a System String. I am able to display the data in a text box but now I want to work on it! The data is from a hardware device so there are a few states that I need to display. Each string begins with a U, I, O, or P. There is some 0's and 1's and ends with a carriage return, line feed. When the program sees a \r\n I want to the program to examine what was received and give the correct output accordingly. I assume that I will need to read the data received into an array - but each time I try, I get error messages relating to the fact that you cannot convert a system string into a char or int. How would I store the string data that is received How do I then lo ...Show All
