I am noticing a "mysterious" change to text files used for graphs using Zedgraph libraries.In a 100-line data set, about four to five records inexplicably "disappear"! These are the SAME files which only 24 hours earlier showed the complete set and were successfully read.

If you're familiar with the Kellerman FTP Library, that is the paradigm I have in mind -- i.e., add an import, declare an object and you have every FTP function you'd ever want, with simple syntax.

View 1 RepliesI am using zedgraph to draw bar chart in my vb.net project. The bar base is Y (meaning all bars are horizontal). I have 9 fields for user to choose from, and once a user clicks a field, one corresponding bar will show. Of course, the user can click off the selected field to remove the corresponding bar item. I can do this. The basic idea is to get all bar items and set their visibility according to user's selection. My problems is that I want to have a textlabel next to each bar (this text label is different from legend)so I set the yAxis.Type=text. There are two problems:
1) When I add bars, I still need to specify x and y value. How do I set y value in this case to make sure bar ally perfect with its text?
2) As far as I know, I can add text labels by an array as the last line code shows. But obviously this only works for bar chart with fixed bars. In my case, the number of bars and also the order is changing based on user selection. How can I set text labels?

I am following the tutorial here: [URL] But I'm having trouble with Part 4: [URL] With one caveat, I'm writing code in VB.Net. With that said, I've completed Part 3 and been able create a new module (just by adding a simple Class Library) and having Orchard recognize and enable it.

I am working on a program that opens forms from within the startup form. It is doing nothing usual that I am aware of. It was working fine an hour ago but now when I try to open one particular form I get the InvalidOperationException and I have no idea why. I've rebuilt the project, restarted VS2008 and restarted the computer. The other forms open without any trouble.

View 10 RepliesI designed 7 class libraries for 1 project.The project references all 7 libraries.3 of the 7 libraries make references to the other 4 libraries.I thought of just duplicating the code that's referenced in the other 4 libraries, but thats a lot of code.
Example:
PrjctA makes reference to LibA, LibB, LibC, & LibD.If LibA references LibB & LibC also will this fail?

Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try
Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
infoDisplay.AppendText(fileText)
infoDisplay.Rtf.Format()
Catch
MsgBox("Selected Hero currently has no File with us.")
End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\f0\fs20{\object\objemb{\*\objclass Paint.Picture}\objw3000\objh3000{\*\objdata

Ok so im not sure how i can read from a RTF file and put it in the RTF box with the right format....Ive been searching around for a while.
On a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.

I have successfully created excel application, workbook, worksheet and graphs in excel through vb.net, but I am not able to choose which data to plot on teh x-axis when I plot graphs.I don't really know how to do this even in excel itself, and googling did not help at all...how to create a graph with desired values on the x axis in excel through vb.net, that would be nice.
range1 = Data.Range("A1", "B" & (t2 - t1) / i)
graph1.SetSourceData(Source:=range1)
This is my code, since I have index (t2-t1)/i as the index of the data I want to plot on the y-axis, and I want to plot all A1 values on the x-axis.
Tabpages: Using a button, how do I go from tabpage1 to tabpage2? I have it kind of sorted, only not: Button click tabpage1 send to back() or hide() tabpage2 show() The problem with this, is it does not actually turn the page, and the tabpage1 tab still shows at the top. Decimals: Epically basic, I guess. I have calculations that does, for example: 10/6 = 1.666666666667 How do I get it to say 1.667 only?
And Lastly, Graphs: I have a line graph. I have fixed series as a envelope for the variable series to sit in. Again, epically basic - How do I make a series that draws a line for a variable?

View 2 RepliesI try to detect when the mouse is over a curve in zedgraph, I am capable of doing it if the mouse is over a point of the curve, but the problem is when the curve has no points in that region,let me show you an example:
Curve is defined by 2 points: [X=0;Y=10] -- [X=1000;Y=10]
If mouse is at point [X=500;Y=10] it is over the curve, but not over any point so i cannot detect it.Is there any event which gets fired when mouse is over line but not necessarily over a point?
Im using ZedGraph and want to do things as points are hovered over ("show point values" has to be on). is there an event i can harness that fires when you hover over points?
