Remember Variables Which Were Completely Dependent Upon Count?
Oct 6, 2010
So I am working on a project for class. I first hit a bump when I could not figure out how to get this to count the number of times the button was clicked. Now I have hit a road block. Here is what I have so far (I stopped where I couldn't get it to work):[code]How can I get this to remember variables which were completely dependent upon the count?The project is asking for 5 prices entered 1 at a time, clicking the button ("Include Price"). After each number is enter, I am supposed to be getting the largest, lowest, and average of the numbers.

I have set up a simple quiz where you drop answers to the correct question. I have implemented a system where the are 18 text boxes (9 for questions, 9 for answers) and it can be customised but I want the questions to be able to be 'saved's since it in another form the if I give them special names when I close the form and open it again it has lost the values. Is there a way to remember the variables for a set period of time (cookies?) or if not just for that session?

I want to pass a few variables to another page. Currently I'm using response.redirect and passing the variables in the url. I'm not really interested in using Session Variables. Is there a way to pass hidden variables in .NET to a completely different form?

I was wondering if it is possible to have dependent types in VB.Net 4, or alternatively, if it is possible to construct inherited objects based on the base class' constructor's parameter(s). For example,

I have a spreadsheet that has two columns (A and B) - Column A contains Month/Year and column B contains sales. I would like a bit of vba that will look in column A to find the month/year then calculate from column B the average sales for that period. So for example:
Date Sales
Jan 11 500.00
Jan 11 250.00
Mar 11 152.00
Apr 11 116.00
So in other words there can be a number of lines with the same date/year and the code will need to identify these and average all sales from column B associated with that particular date. I would like the output to appear in a summary table showing the total average sales for each particular month - perhaps this could be output to a new sheet?

I have developed an application in VB.net which uses R Programming language. The library that help connect VB.net to R is called R-DCOM. The application requires the user to install R-Programming language into the user's computer. The application was working all fine until there was a version change in the R-Programming language. The specific libraries involved with this are: Interop.STATCONNECTORCLNTLib.dll, Interop.StatConnectorCommonLib.dll and Interop.STATCONNECTORSRVLib.dll. It also uses StatConnectorClnt.tlb, StatConnectorSrv.exe and StatConnLib.tlb to run the application. Is this something related to "DLL hell". Is there a fix to that I may not have to recompile and install the original code and install them to the user's computer all over again.

There are several times in my code when I need to determine the width of some text. Under VB6 I would use the .textwidth() method pretty much any time I wished.Under VB.NET it appears that the paint event is the only place I can gain access to an initialized graphics object and from that the measurestring() method.Do I have to use a flag in the paint event when want to auto-resize my splitterbar position or is there another way?

I have developed an application with a plugin architecture using interfaces. I realized that when I release the API for 3rd party plugin development, someone would be able to create a loader program to replace my main program quite easily. Is there any way I can make the plugin dependent on my main program? All my main program does is get an icon and a description of the plugin from the DLL plugin (using the interface) and then calls the dll's interface function to create and display the form.

how you populate cascading comboboxes? I have one combobox on one form, from which I'm trying to populate another combobox on another form. The first combobox contains Locations while the second combobox contains offices for whichever location is selected in the first combobox. I would like it to work as follows: user clicks on first combobox to select a location, and then the second combobox lists all the offices for that location.As of right now, the second combobox is just displaying the first office that is in the first record for the respective database table it is pulling from.

I'm using RichTextFormat, and i'm using cf to change the color of strings. I have this
Code:
cf22dgreengiant
Its actually like this though
Code:
cf2 2dgreengiant
But the parser thinks that the 2 in his name is part of cf. There's a character, in many different formats (usually ) that will fix it, but I can't remember what those characters are called so I can't look it up. It would be like this, assuming ! was the character. This would make it parse correctly
Code:
cf2!2dgreengiant
So what is that character called? Sorry for the dumb question, but I can't for the life of me remember.

How I can populate a combobox (combobox2) based on the selection made from another combobox (combobox1)? They are on different forms. Combobox1 lists locations, while combobox2 lists offices for each location. I would like it to work so that when the user clicks on combobox1 and makes a selection, the 2nd form loads with combobox2 showing all the offices for the selected location.

I have some reports that I use with the MS ReportViewer and I need to get a count of the physical pages (as opposed to logical page count) to use with a print dialog. I've implemented a workaround so the ReportViewer control displays the correct number of physical pages, but is there a way to get that value from the ReportViewer control? The only publicly accessible property gives the logical page count.

designing a Windows based computer program that will allow a user to enter some number (n) and a choice of a count up or count down for that many numbers. So for example, the user enters 5 as their number and selects the count down option, the message box displayed would contain the message: "Here are your numbers: 5,4,3,2,1,0"

I have a master page called SampleMaster.master and this page contains a Repeater control
The Repeater control will be used to display the relevant tags associated with each content page and the tags will vary between content pages
The data extraction method Tags.GetTags() is working but I do not know the best approach to populate the Repeater control in the master page dependent on what the content page is.
Would the code reside in the masterpage page code behind or the content page code behind?

Below is my code. I have a system that provides me voltage readings that changes based on a timer (interval of 300 milliseconds). I want to compile voltage readings for over 5 seconds (but I need the timer reading to remain at 300 ms) and then spit out an average of the THAT data. How do I do this? I was thinking of using datasetvalue but wasn't sure.

I am using TPT modeling and writing the EDMX by hand as our data model is much more complex than the designer can support. My model includes a ProjectObject which has a dependent object name Project. When I query ProjectObject.OfType(Project) using Linq to SQL, I receive back data in all the fields that are inherited from ProjectObject, but no data in the fields that only in Project. I have ran a SQL Server Trace and captured the actual SQL and ran it using SSMS and it returns data there, so I am relatively certain the data is being passed back, but it seems to be getting lost somewhere in EF. Everything appears to be ok in my model, but . . .

VS2008 / XP Pro sp3 / .NET 3.5 I develop during the day on my office computer and bring home projects on a laptop to work on over the weekend. After working at home then at work, I have a conflict that I don't understand. When I build, all is normal but when I debug, I get "Found conflicts between different versions of the same dependent assembly." If I click on the warning message I also get "Do you want to fix these conflicts by adding binding redirect records in the app.config file"?Both computers have same O/S, same SP, same .NET, same VS. Only thing that could be different is particular O/S updates that have been installed on each machine. What causes this warning and where do I look for differences? I really hate to let mSoft keep changing my code every Saturday and Monday. I just don't trust it on Mondays.

Is there a way to make one list box dependent on the other based on user input. Here's my situation: A teacher has the ability to enter the name of the student into a listbox via a textbox. The teacher may then select the student from the first student list box and input grades that would go into a grade listbox. If the teacher selects another student from the student list box, the grade listbox would either go empty or show the grades inputed for the other student; all the while retaining all previously recorded grades for other students.

I have a slight problem , using vb 2008 i have written some code that checks the current datetime on the computer. This gives me the answer in the format mon, tues etc. what i now want to do is to use that to call a spreadsheet dependent on the day of the week. here is my code so far
Code:
Dim TIME As DateTime = DateTime.Now
Dim FORMAT As String = " ddd "
TextBox1.Text = TIME.ToString(FORMAT)
[Code]....
Now i have tried the private sub eg SATS() on a separate button and it works perfectly . so it appears to be that the sub is not been called. I think it is probably a syntax where the datetime answer is not been recognised, in that textbox1.text = "sat" is not the same as datetime = sat .

How can i get my program to remember settings?I have made it so that they click on a register button, if they enter the correct registration code, it will unlock these features. How can i make it so it remembers that the key has been inserted, so when the user next uses the program, they dont have to re enter the key. I think it has something to do with ini files, but im not sure how i can implement it.Here is the
