Open Second Form Based On User Input?
Apr 14, 2009
I am working on a project using Visual Studio .NET 2003.I am trying to open a second form based on user response to Yes/No Message Box. I have tried two different code variations. The first variation is:
Dim MsgAnswer As Boolean
MsgAnswer = True
Dim MsgRes As DialogResult
Dim CustomerInfo1 As New Form
[code]....
With this code I get an exception error: An unhandled exception of type 'System.NullReferenceException' occurred in OrpheyOnOpen.exe Additional information: Object reference not set to an instance of an object.

I've been working on an application for awhile that, basically, allows the viewing and printing of a maintenance database. It allows the user to view basic information for the object and then view the maintenance history. My approach for the maintenance history is simply to have unique tables per object since a history has to be kept for each, however, I'm running into a problem in the application that allows the user to view the general information from one DB and the Maintenance history from the other DB.
Say you have Object ID BG1. I can enter the object ID into a search field, pull the data from the general DB and display the data, but I also need it to pull the information from the maintenance history and display. If maintenance history for this object is not found, then create a new table within the DB, fill the columns with the required fields and allow for the user to edit the history.

What i am trying to achieve is that there are 7 columns in my db table. one is primary key and rest 6 are integer columns. Now my application will allow user to input 6 values. I want to compare 6 values entered by user to those 6 integer columns and if in any row 3 or more columns match user's input Primary key of that table is returned..I have tried using queries, cursor, nested loops and i am still unable to achieve my results..
UPDATED :DB Table Structure.. I am inputting 2,3,7,11,45,65. Number of returned rows should be 5. eg..
UID A1 A2 A3 A4 A5 A6
-----------------------
1 2 3 4 5 6 7
2 2 3 4 55 56 57
3 65 11 45 66 67 68
[code]....
IDs returned should be 1,3,4,9,10

I have 10 constant arrays of data that can be used throughout the program.[code]I also have an array that needs to be populated randomly depending on user input.array_user(8)If the user selects 3 for instance...I need the data in array_user to be populated by the data in array03.I know I can do that with if/then statements...but I'm sure there is a much simpler way to do it.

I have a SQL db that holds the records for my page. On my page I have a details view I want to populate with records from my db. I can populate the records just fine, I need to be able to populate in records based on a user selection from a drop box?To clarify, on my main page I have a drop down list with years (ie. 2011, 2010, 2009), and a drop down containing account codes (ie. six-digit numbers). Based on what the user chooses for the year (for example 2010) and the what they choose for the account code (for example 123456) I want to populate the details view (which is on a seperate page) with only those records from 2010 and with the account code 123456??

I'm trying to do the following.I want to use a gridview to load a set of associated records dynamically based upon the input of the user.I want the gridview to have a checkbox to the left of the records and allow the user to use this to select records to remove. The gridview will have pages and will be sortable using the columns.I had this working using a delete button, but when I went to using the checkbox it stopped sorting.

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 am attempting to set up a datagridview that is dynamic based on user input. The user input is a start and end date. The start date defines the first column the next column is the next date... until the end date (x-axis). The y-axis is technicians and the fields will show the assignment for the technician on that date.
All the advise I am seeing on datagridviews is to create a property methods to provide the information for each column. for example:
Dim 12-Oct-2009 as string
Dim 13-Oct-2009 as string
[Code]...
How do I create a object data source that allows me to populate the data grid? I want the column headers to be included as a string in row 0 of the multidimensional array. The amount of columns will be dynamic with a minimum of 1 and maximum viewing of 100 days based on what dates are selected in the start date and end date fields.The input dates will be used to generate a query to a database that will populate the multidimensional array.One solution I see is pick a start date and have a set number of dates and code for set number of columns (100) in a row and then set the names of the columns dynamically...ahhhh code repetition!
I am not sure how else to do this but looking for a more suttle way.I am using this to create a simple scheduling tool to see resource schedules by date. There is an unmoveable end date so initially I will need to look ahead 100 days but as the end date gets closer, I will have fewer and fewer dates. So eventually the end date will be that start date.

Private Sub TrackBar1_ValueChanged(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles Trackbar.ValueChanged
txtYears.Text = Trackbar.Value
End Sub
This is the code for the trackbar. At the moment as the user moves the trackbar it inserts the value into the textbox. I want this to work in reverse also. user inputs value into text box, trackbar moves.
I know it is possible as my professors program does this.

I don't like validating through the TextChanged event either as I believe that to be the cause of some issues. Doesn't the Textchanged event validate on each time a letter is typed?

In this application I need to allow users to enter a month as integer (1-12) then use integer tryparse to validate that input, that seems to be the easy part. I need two create two functions, one that returns the name of the month and the other returns the number of days in that month. The arrays are supposed to be defined and initialized within the function so that the main program can take the user input and call the two functions, then return the appropriate values as output to labels. I am not sure how to declare the arrays in their appropriate functions and then how to call those functions to retrieve the right value from the function.

I have a procedure at the end of my console application that ask the user to either hit enter to end the program, or type s to perform another search. The issue I'm having is no matter what the user types in the program end. What I would like to happen is if the user types s, then the program starts over and lets the user perform another search. The program is procedural and I need to find a way to start back off at the top of the program which ask the user to type a name to search.

I am developing a software using microsoft visual studio basic 2010. I used a datagridview control to display a list of data from product table. What I want to do (actually I am not sure how to do it, or is there a way to do it), when I choose one of the value in one of the column inside the table, I want it to open a form that contain data(details) based on that value.
How to do it? How to call the value that I pressed, so it can be used to open a new form containing the details of that value
Example of the data: (the "system" column) SYSTEM
topaz
nex1300
Nec
If I pressed "topaz" system, it will prompt me to a new form containing the details of that "topaz" system.

I would like to develop a structure to maintain my user's text input somehow on each form to allow user to return to the form and see the prior input for potential editing. My app has four forms which accept user input and form a string for output to printer. In the eventuality that the user notes a mistake in the input after leaving the app, I would like to develop a structure to "save" the user input at the form level and allow for repopulating the text boxes with the prior user input. Make sense? I have no idea how accomplish that functionality. Maybe it's too complex for my purposes. What do the pros think?

how to create a form that allows a user to load an input file? I'm assuming a form like a windows explorer window will be too difficult, or not? If it is then I guess I could just put a textbox on the form and ask the user to input the directory with file name.

I'm trying to make a form that takes user input 3 times, and each time compares it to the correct Answer... which is an array of {"C", "D", "A"}.Each time the user's input matches the correct answer ("strCorrectAnswer()"), then I'll add 1 point to intUserScoreCounter. I'm wondering why this code is returning an error (hilighted in blue)? Can I not compare a String to an Array?

i have a access database with two tables, one for customer and one for booking.
I then have a form application i made in VS 2008 which lets a user enter details such as their name phone number ect into text boxes.
All of the information the person enters thoughout the program is shown via labels at the end, all on one form.
Would it be possible to then have a button that when clicked saves all of this information into the access tables into the correct columns, im sure it must be possible i just don't really know where to start.

I am trying to figure out how to generate code from user input. In Visual Studio 2008, Visual Basic.My script always begins with:function Init (Quest)Then from here a user would input a quest name, type and zone in a interface using windows forms.[code]I would also like to have these available on the UI but wont generate unless a user checks a box to add them or there is a box already for them but wont step into the code unless the user enters something into the box.Is there anyone that can explain how I would go about doing this. Or maybe some kind of visual studio plugin that will help me out.

How to generate code from user input. In Visual Studio 2008, Visual Basic. My script always begins with:
Code:
function Init(Quest)
Then from here a user would input a quest name, type and zone in a interface using windows forms.
Ex:
Code:
RegisterQuest(Quest, "Kill Zombies", "Heritage", "Firestorm")
end
This part a user would enter in his interface what would an NPC say if accepted.
[Code] .....
What I need is a few text boxs that a user can input "Kill Zombies" or whatever they like and when they push a generate button it will create a file with a .quest extension. All of the code remains the same except for the quotes that would be the user input from the interface. Basically everything in quotes can be changed by the user in an interface. I have created my own functions for when a user accepts, deny and complete a quest. The user just needs to input what should happen then click a generate button to throw it all together as a .quest file to be saved in his or her quest folder for the server to call on later.
I also have many other functions like:
AddQuestRewardFaction --- (Quest, Faction ID, Amount)
AddQuestRewardCoin --- (Quest, Copper, Silver, Gold, Plat)
AddQuestStepObtainItem --- (Quest, Step ID, Description, Quantity, Percentage, TaskGroupText, Item ID(s))
Etc
I would also like to have these available on the UI but wont generate unless a user checks a box to add them or there is a box already for them but wont step into the code unless the user enters something into the box.
