Form Background Subclassing mdb30-Dec-03 11:31 mdb 30-Dec-03 11:31  i'm using the cTextBoxBackground class from vbAccelerator http://www.vbaccelerator.com/home/VB/Code/Libraries/Subclassing/Tile_a_Bitmap_Into_a_TextBox/article.asp and trying to adapt it to change the background of a form (which i don't own), and it almost works. If you remove the lines which refer to the hWnd of the parent window and use the class "as is" to subclass a form it works except the labels are not drawn onto the DC, nor are shapes and lines etc. these controls don't seems to get painted onto the DC when you send the WM_PRINT message. does anyone know of a way around this. Thank you mdb Problems with Bootstrapper plug-in. jlizardo30-Dec-03 9:37 jlizardo 30-Dec-03 9:37  Hi I Already follow the instructions to configure the .NET environment.

How to skip a few lines while reading from a text file? ESJY30-Dec-03 4:26 ESJY 30-Dec-03 4:26  i m currently working on a program which is able to read a text file. however, i have encountered this problem while extracting information from the text. first i have to reach a keyword found in the text (which i have successfully implemented), then i have to skip a few lines after the keyword to extract the useful information. i have no idea on how to skip the lines while the program is reading the information from the file. i think it is not wise to load everything into the program, which takes up memory, and discard. could anyone suggest on how to ignore the useless information? Thanks. Esther Re: How to skip a few lines while reading from a text file? Anonymous30-Dec-03 8:16 Anonymous 30-Dec-03 8:16  Simple. Just read the line, or lines, you want to skip and don't do anything with them. You'll probably want to read the exact number of lines you want to skip inside a for/next loop. Dim strDiscard as String For x = 1 to n strDiscard = ReadLine(filepointer) ' or whatever your using to read a line from the file Next Re: How to skip a few lines while reading from a text file?

In the project we have to draw a regression line on a graph. First the graph is plotted against the two axis and after setting all the points the regressiopn line is to be drawn.. Also the equation for the regression line and the equation of the line are to be found Please let me know the solution for the problem as soon as possible with code if possible regards ManisH Circle geometry cnurse30-Dec-03 0:47 cnurse 30-Dec-03 0:47  Boy! I wish I paid attention in maths class instead of reading Visual Basic Programmer's Journal! (yeh right!) Can any kind soul give me a function which returns a Point object, where the point is a set number of degrees around a circle which fits inside a given rectangle. I know that's an odd way to describe it! Dim lRect As Rectangle = new Rectangle(0,0,100,100) Dim lPoint1 As Point = PointOnCircle(lRect,45) Dim lPoint2 As Point = PointOnCircle(lRect,135) The above two calls will acquire Points where the X,Y coordinates are at 45 degrees around the circle (which fits in a rectangle of 100,100) and 135 degrees respectively. The bit that gets me is the X= some sin/cos nonsense and Y= the other bit (and those bl**dy radians are involved aren't they). Maybe I did keep one eye on the blackboard. I would be prepared to have your babies if you can pull this one off for me (which I am just sure you are dying to know how I will manage that!). Thanks! Ps: Sorry for all the !!! in here, well it is New Year and all that!! oops! damn! can't stop it!

Eman Ali Moughal Senior Software Engineer Soon Soft (pvt) Ltd www.soonsoft.com Re: Help me How Exacrly i can use the pathGradiant brush cnurse30-Dec-03 4:40 cnurse 30-Dec-03 4:40  Eman, I just hacked this code out of my own C# project, hoping thatit will be of use to you. It may help clarify a few quirky things about PathGradientBrush. I think, by altering the focus parameter of SetTriangle... or SetSigma... in the code below, that you may be able to present a highlite at a position in a circle which approximates the look of a sphere. I honestly dont think you will get anything high quality though without breaking the sphere into triangles and shading each one appropriately, and that's way beyond me. Another kludge you might use is to take a bitmap of a sphere, drawn in a 3D package or using Photopaint etc., and scaling it. Well, for what its worth, here is my code, you will have to hack out my variables and try follow what's going on quite closely. This method returns a brush that you can use on Graphics.FillPath. prPath is a GraphicsPath prFlip just flips a start and end color around prBrushType is my enumeration which controls whether blends or triangle or bell type fills public PathGradientBrush CreatePathBrush(GraphicsPath prPath) { Color lStart, lEnd; // Start and end color PathGradientBrush lBrush; // Brush to assign to lStart = Your Start Color; lEnd = Your End Color; // Create the linear brush lBrush = new PathGradientBrush(prPath); lBrush.CenterColor = lEnd; // Create an array of colors which are the end color at each point Color []lColors = new Color[prPath.PointCount]; for(int lCount = 0 ; lCount < prPath.PointCount ; lCount ++) { lColors[lCount] = lStart; } lBrush.SurroundColors = lColors; // Experiment with the 0.5F figure, it should change the highlight on the shape you fill // Of course you will want to fill a circle or ellipse would be better still. lBrush.SetSigmaBellShape(0.5F); return lBrush; } --------------- Hope this makes some kind of sense to you.

Member 76608429-Dec-03 18:49 Member 766084 29-Dec-03 18:49  Hi.. I have created 3 different application.out of 3 ,one is taking care of "sales automation",second is "sales account" and last application is taking care of all MASTERS .so i want implement this in one deployment package.for example in oreder to implement in client side ,i would require a check box along with all this application name,where i can select which app is require and which is not require.so it would be easier for me to select app name accroding to users requirement.ex:an administartor might require all the application where as a normal user require only "Sales Automation" part,and a account person might require "Sales Account" part.In order to differentiate and implement i require all the application in a single deployment package other than having different 3 deployment package. If any one know this ,please help me Thanxs in Advance Oppinions of serialization cnurse29-Dec-03 13:51 cnurse 29-Dec-03 13:51  I am just beginning serialization on .NET, having dealt with it many times before with other systems. I have been told serialization using the XML serializer is simple, and the documentation makes it appear so. But, do I have to make all my properties public? I create accessors for all properties, as its easier to debug things that way, and some of my properties are read-only. I can't go making my internal member variables public, that would be crazy, so what do you do about it? (By the way, if you don't think it is crazy to make your member variables public, then how would you do range checking and protect yourself against corrupted data on de-serialization?) I'm about to start writing my own serialization code for each class, so a quick guide would be really appreciated. I don't care if its XML or binary format, I guess there's really not much difference from a coding point of view anyway. Many thanks, and a Happy New Year to all. Nursey API Calls or VB.NET Code Don Hamilton29-Dec-03 11:50 Don Hamilton 29-Dec-03 11:50  Can anyone tell me either API calls or VB.NET code to do the follow steps or items. 1. Start Windows Explorer. (ProcID = Shell("C:\Winnt\explorer.exe)) 2. Size Window Explorer and set it's position. 3. Set Initial Folder. 4. Set Filter on files shown. (Not a must but would be nice.) 5. Recieve Event or know they have closed Window explorer with my ProcID. Any assistance would be great. Thanks Don Don Hamilton VantageMed Corporation - Kansas City
