I recently found an awesome tool called "Freemind" that is called a 'mind mapping' program. It's similar to MS Visio but way cooler and more automated.I reeeallly would like to integrate this into a VB.net Form, but how?
Has anyone seen or heard of mind mapping inside VB.net before? Are there programs out there already that work with VB.net or anyone have an example they have seen / built that works?
I wrote a C# Excel automation addin (Excel 2010 64bit, VS 2010) to provide some additional user-defined-functions in Excel. Now, the addin works fine besides the fact that the two methods "OnDisconnection" and "OnBeginShutDown". are not called when I close Excel which is a problem for me. Also, while Excel seems to shut down properly, the instance is still running in the background after the excel-window has disappeared. So, apperently the problem is that Excel is not shut down properly.
View 2 Repliesi was wondering if it possible to have a condition where lets say you have a column in the datatable called amount and a textbox acting as the filter called say maxamount to set it so the rowfilter when filtering the table will sum the number in the amount column until the number in maxamount is met, then stop and only return the rows where the total sum of the amount column is equal or less than the maxamount value, so i guess if the next row takes us over the maxamount it discards this row and returns the rows previous to it. is this possible using datagridview rowfilter or should i be loooking elsewhere to achieve this?

I have a form called FrmPracDetails which is built up with a List view called LvwColProc. Therefore when you click a field on the LvwColProc it takes you to another form called FrmColProcessing, here you can make changes to certain fields which are also present on FrmPracDetails. What I want to do is when you make changes on FrmColProcesing and Click the Save Button (which calls the Save function)the changes appear instantly on FrmPracDetails. Please note, FrmColProcessing will always be open next to FrmPracDetails. I have tried to put this code in the Save function present in FrmCol Processing as shown below, but it doesnt Refresh FrmPracDetails form. [code]
View 1 RepliesI have the following line of code in my program:
JCL_History.Enqueue(JCL_History(I))
This JCL_History object is basically a Generic.List encapsulated in a wrapper and has the following method:
Public Sub Enqueue(ByRef value As String)
If Members.Contains(value) Then
Me.RemoveAt(Members.IndexOf(value))
[Code].....
In my testing I have 2 items in this JCL_History list. When I call that first line of code I posted (the one that invokes Enqueue) with I = 1 I expect the first item to be shuffled to the bottom and the second item to be shuffled to the top.
After the thread returns from Enqueue I notice that this is exactly what happens to my list, HOWEVER if I hit the "step_in" button after the execution of Enqueue I go into the Default Property's set method where Index = 1 and value = and it screws everything up, because the item that got shuffled to the end (index 1) gets overwritten by the item value shuffled to the top.
So basically the set method on the default property is getting called at what I think to be a completely ridiculous time. What gives? By the way I'm running VS2005 on XP.
Can you look at my coding and let me know what I'm missing or doing wrong?I have a SSRS report that is called from a ReportViewer control and the ProcessingMode for this control is Remote. The report also has 1 parameter in it's DataSet.In the code I placed a MsgBox to make sure the code is finding the parameter and returning the parameter name. I am trying to stick the value of 10 into the parameter for playerID 10. Data for this player does exist.
I believe I need to add some more code to make this work but I'm not sure what else to add.
When the code executes the report is displayed but no data is shown in the report.

I'm writing a program and have run into a bit of a snag. I have the code perform a button click on certain buttons, the reason for this is I have a bunch of buttons that each do something and one that does everything automatically. I suppose I could rewrite everything under that one button but that would essentially double the size of my program, I could use an if statement to catch the fact that the program is in automatic mode but that would be about 15 conditions (not looking forward to writing that statement ;p)
Clicking the buttons is a nice simple, clean solution. The exception being the program performs the click then continues on executing the rest of the code in the actually clicked button while at the same time executing the code called by the code click. Main problem with this is the data that needs to be populated by the code click isn't being populated fast enough for the code in the main button so then there is errors, blank data, program doing nothing. A simple sw timer to delay could work (I know how to make one of those) but the problem with that is the program is executing against a webpage and if the webpage takes a few seconds longer to load then anticipated everything is out of wack again. I'm looking for a simplish way to cause the program to wait for ALL code called by any raised event to finish before proceeding.
i.e. Call Button.clickEvent > Wait for code and subroutines executed by Button.clickEvent to finish > continue with rest of code in button.
Below is the code I'm using so far for the user clicked button.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Button4.PerformClick()
'Need to wait for all code executed by Button4 and anything it calls to finish

i'm creating a program called Workshop Selector. It has 3 list boxes, one with the 5 workshops, second with 6 locations, and the final is the list of costs. The user selects a workshop, a location, then hits the Add Workshop button, which calculates the costs and adds the cost to the third listbox. Soo, to my question.
There is an additional button called Calculate Total that adds the values of the costs in the cost listbox and displays the total in a textbox. The code i currently have that works just fine is --
Dim one, two, three, four, five, total As Integer
lbCost.SelectedIndex = 0
one = CInt(lbCost.SelectedItem.ToString)
lbCost.SelectedIndex = 1
two = CInt(lbCost.SelectedItem.ToString)
etc..etc..
total = one + two + three + four + five
tbxTotal.text = total
While this works, i have no idea of knowing how many times the user will add a cost to the cost listbox. therefore id have to make many many variables, and other issues occur.So is there a way i can do this with a for loop? declare a global variable like
Dim costcounter as integer
then at the end of the add workshop cost btn click procedure use:
costcounter = costcounter + 1
That way i kno the exact amount of times the person added a cost?
Then create a for loop like
Dim intcount As Integer
For intcount = 1 To costcounter
code....
Next
Would this work somehow? but what code would i have to input within the for loop to scan each selected index, and then return values that can be added together and displayed in a textbox?
Ok ive managed to figure our most of my problems, and get help , from u nice people. i have 88 buttons and 1 is visible by default the rest are invisible so if you click the first button you get a open dialogue to select a program for my app called winhome after that i need the second button to become visible, and so on,any quicker way to do this instead of manually copying/pasting if statements?

I have been developing a calculator for complex math. (Much more complicated than +,-,/,*, and above your usual scientific calculator)Its works quite well .In past programs I have used "private functions". I know that you give them a value and it returns on back. But what if you dont want to recive or send value? My example for this is a function I am attempting to make called "Autopi".The idea of Autopi is that whenever a mathimatical operation is about to be performed textbox(s) are cheked to see if they contain pi. (3.14 or 3.141) If they test positive Autopi will continue pi to however many places have been specifyed in the program. (Currently 300 places just beacuse i can :) Before the Autopi function does this it chekes to see if variable "pi" = 1. If it does it proceeds if it doesent its job is done

It appears that when one creates an instance of Excel, using CreateObject, (Late binding), the suggested Excel closing function (with GC.collect etc) does not work. I have tried several suggestions, and the only one that works is process.kill method. Do you see any problem in using this? BTW: the reason we are using late binding is that we cannot use Office PIAs....not sure which version of Office would be installed on the client site. We work with O2003, but the client might still be at 2000 or 2002.

Ok basically what I need to do is the following:Read FirstExcelDoc (attached)For every row in that: Retrieve data from sql server db based on info in the Orange columns of FirstExcelDoc Let's say I retrieved data elements A, B, C, D, and E from sql server. Then I need to enter those same data elements A, B, and C in another excel spreadsheet (which has formulas etc) After inputing A, B, and C in that spreadsheet, read a couple of calculated fields and compare those results to data elements D and E retrieved originally from SQL Server DB. Finally, output the results in the Blue columns of the FirstExcelDoc spreadsheet for that row.Loop through and do the same thing for row 2 of the FirstExcelDoc and keep on until you see "END TEST" in the FirstExcelDoc.
I'm looking for a method of doing this efficiently. I have read several articles over the past few days as well as those from Mike R. but just need some direction to get started on this.To start of I'm looking for whether to read the entire FirstExcelDoc spreadsheet or just read the info for first policy number(2nd row) and process it and write out the blue column info for that row and then loop through and come back and read the second policy number (3rd row) etc... Please attach a code snippet for either way of reading the data.
I'm using excel via interop in application.Sometimes users kill application that created excel instance and that results in excel instance sitting in memory without any chance of disposing it.First I tried to tackle this using ROT(running object table) looks like not all instances of excel are registered there.Than I tried to somehow mark excel process after it is started via interop.[code]This works as long as excel is visible but in my case excel window is invisible.All I need is to somehow mark process that started via automation with the parent PID, so that later I can kill it if parent does not exist.

We have a vb program which is run on our server by scheduled task every day. The program opens about 30 excel files, refreshes the data connections, pivot tables and then saves the document in another location.
This may run fine for a couple days but sooner or later the process starts crashing, usually with this error: RPC_E_SERVERFAULT.
My question is, Is it expected that continually opening/closing/refreshing workbooks will inevitably cause the Excel object to crash at some point.
