• Visual FoxPro Cannot execute program outside VFP9 IDE.

  I have built my VFP9 application into both .app and .exe files and when I execute them, the VFP9 IDE starts up and runs the program inside of the VFP9 programming environment. As a result I cannot see how the program behaves on its own as if it were installed on a client's machine who does not have VFP9 installed. Could someone please indicate how I can run an application on its own without it having to run within the VFP9 IDE Thanks Hi, To hide VFP main screen, you can put code below at your main prg _SCREEN.VISIBLE = .F. Or Create file called config.fpw, put the following and include into your project SCREEN=OFF Do make sure that your main screen is set TOP LEVEL FORM. Otherwise, you will not able to se ...Show All

• SQL Server FYI: Using Try's with Finally

  Within my script component I was having some difficulty getting nested Exceptions to bubble out of the script component logic. The symptom appears when you get an ex.message of "Object reference not set to an instance of an object." As soon as I removed the Finally section my message (or the actual Exception object) was properly passed to the caller. I've only done minimal work with Try/Catch/Finally structures. Is this normal Thanks, Jeff Tolman E&M Electric Is the sqlReader variable initialized Most likely, when the first exception occurs, sqlReader is not assigned anything. So when you try to close null object, you get the new "Object reference not set to an instance of an ...Show All

• .NET Development System.IO.File.Encrypt()

  I would like to know what specific encryption algorithm (TripleDES, SHA1, RSA, etc.) this method uses. MSDN says: "Both the Encrypt method and the Decrypt method use the cryptographic service provider (CSP) installed on the computer and the file encryption keys of the process calling the method." Can anyone explain to me what they mean by the CSP installed on the computer and if there is any additional documentation this Thanks! This is the default encryption algorithm that is also available through the properties window of a file. You can let Windows encrypt the file. This is an NTFS feature. The algorithm are the following: DESX (Windows 2000 onward), Triple DES (Windows XP onward) ...Show All

• Software Development for Windows Vista Database for samples ?

  Hi Where can I find database for samples from netfx3.com I was looking in workflow's samples and some of them need database but it's not provided. So where it can be found Jedrzej I've found it already I made stupid mistake when I was unpacking file... I had a lot of files in my current directory but I thought it'll give me another nice directory. When I saw dir with name ExternalRuleSet I was 100% sure it really created catalog and full content of the executable is there. But I got another example and I noticed it doesn't create directory :) so... Thanks ;) Jedrzej ...Show All

• Windows Forms Monitoring Changes on a Tab Page

  In my WinForms app I have a tab page with a bunch of controls on it (e.g. textboxes, checkboxes, buttons, radio buttons, etc.). Is there an event, or a few events, of the tab page that I can monitor to see if any changes to any controls on the tab page have been made Robert W. http://pocketpollster.com There's things you can do, like iterating through the tabpage's Controls collection and calling AddHandler for their events. However, different controls have different events and different event handler signatures. You'll need some commonality between the controls (like "Click" is usually available). What specifically are you looking for when you say "anything happened" Also look into ...Show All

• Visual Studio ReportViewer Conditional Formatting Anyone?

  Hello, I'm completing an application based on VB2005/SQL2005 Standard using ReportViewer. According to the documentation (see http://msdn2.microsoft.com/en-us/library/ms252095(VS.80).aspx ) conditional formatting is supported. However, when I attempt to implement this, the report text is not formatted, but the color specification text is printed as in "Red", instead of the number printed with red color. I am obviously missing something here - any help is much appreciated. My customer specified conditional formatting in the requirement doc, so it is actually rather important to me... Thanks again!
