VS 2005 Variable From One Form To Another?
Feb 28, 2011
I have two forms and I need to take the values from the first form and add them to the second form. I have tried many things and nothing is being added or changed yet on the second form. The second form has a Panel as a background, then a GroupBox to group items together and then the relevant controls themselves.I have been working at this for the last few hours and not getting anywhere and needs a second pair of eyes.I have tried DirectCast() and it doesnt work. Nothing happens.The data isnt added or the control selection isnt changed. No errors either.I have tried Me.ControlName.Property =FormName.ControlName.Property and it doesnt work. Nothing happens. The data isnt added or the control selection isnt changed. No errors either.Screen shots attached and so is my code.Button Click
vb
Private Sub cmdStartClientSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStartWorkLogEntry.Click

I have one form, which the user enters upto 5 websites then clicks go - I have on the second form, the one with the webbrowser. timer which checks if the web browser is busy then either a green light or black image will be shown along side the assocaited input box on the first form. I am finding it impossible to feed variables into the clock through ByVal, like I would a subroutine or function.

When in the degug mode stepping through code a line at a time, I want to monitor a variable that was created public on another form. It adds the request, but won't shoe me the data. It says I have to ahve an object reference. I don't know what it wants exzactly or how to give it. Here is an example:
I have on form 1 one a variable, Crec. I am in the debugger debugging code in form 2. To access the variable on form one in my code on form 2, I have to use this syntax: form1.crec Now when I put this quickwatch request in, while debugging form 2, it will not let me see the value for form1.Crec It says I need an object reference. Can you tell me I am doing wrong and how to correct it? I'm sure it something simple.

I have the following function that checks if a date is on a holiday or weekend and returns the first non-holiday or weekend date.
vb.net
Private Function CheckDate(ByVal D As Date) As Date
TempDate = D
[code]....
The function does return a date. But when I try to assign it to variable, it assigns a time instead. Both tempdate and newdate are declared as date also.
vb.net
TempDate = CheckDate(NewDate).Date

I have a piece of code that would be greatly reduced if a variable can be used instead of the actual method. (I am using a structure) kinda like the difference between the following code.
srrMulti.mthChildProp1.varRecall = strVarRecall
subPageRef
srrMulti.mthChildProp2.varRecall = strVarRecall

Name 'My Variable' is not declared.or Microsoft.VisualBasic.Right(StringRow, 14)'Microsoft.VisualBasic.Right' is not declared or the module containing it is not loaded in the debugging session

I know this isn't a vb.net question per se, but I hoping that somebody else out there can shed some light on my problem. I have a query that looks like this:
" select count(*) from OBJECT_DESCRIPTION " & _
" where INSTALLATION_ID = @1 " & _
" and SHAPEFILE_ID = @2 " & _
" and SDS_REC_ID = @3 "
I assign the above query to the commandtext of an OracleCommand object. I'm getting the infamous oracle 'illegal variable name/number' error when trying to execute the following code using the above:

Intellisense in VB 2005 Express is showing lots of member items when hovering over a variable instead of showing the variable value. For example, when hovering over DataRow("Field"), instead of showing what's in Field, it shows all the members of the Datarow object.
Is there a way to change this, so I can see variable values without using the debug window like so, ?Datarow("Field")

I have a problem when debugging a code. On top of class I declare an array, and the length of array is an integer variable which is applied value below declaration of array.
E.g. class declaration
Dim array1 (2, integer) as string
Public Sub
integer = 5
End Sub
So basically, array is created with integer being 0 or whatever, because it is declared before integer was assigned a value. But the problem is, I need it to be declared at class variable so I can use array in different subs.

I'm building SQL statements with a bunch of values from a dataset. Obviously that gives some really long names to put inline or even in parameter. addwithvalue code so beforehand I just declare a bunch of variables with really short names and assign them to the DS's exact fields like: [code] but this way I'm putting all the data in the dataset into memory twice by copying it into a new variable, right? So I was thinking, if it's just a string variable representing a field on the dataset, why not declare it by reference so the variable is basically a handy nickname pointing to that field in the dataset.Will it even work to have a string declared by reference and connected to one value inside of a dataset? And if so, will that stop duplicating everything in memory? I forgot how to declare a variable as a reference to another variable instead of the normal way in VB.

I am looping through a spread sheet control that has some part number and a quantity of labels that need to print for each part number. Can I use one print doc and set the copies for each page individually? For instance, I may need 1 label for row one, 3 for row two, and 5 for row 3. Through my testing it looks like it doesn't work that way.

In the application I'm documenting, sometimes a value is stored in a Public variable & other times it's passed to/from a Public Property which does nothing except store it in/retrieve it from a Private variable. (And in one memorable exception, the Public Property stored it in a Public variable-I'm almost certain that was an oversight by the original programmer though.)
I know that passing it to/from the Public Property has the potential for better validation, but if the Property doesn't actually do anything except store/retrieve it is there any benefit to declaring it as a Property? (Or maybe I should put that the other way around. Personally I'd declare them all as properties because that will allow adding validation later-but I'm not rewriting this, I'm just trying to document it and, in this case, trying to figure out why sometimes it's done as a property & sometimes as a Public variable.)

suppose I have variables named A1, A2, A3 ... B1, B2, B3 ... Z97, Z98, Z99. I have a certain operation I want to do using each one in turn. I CAN write a line of code for every single variable, but this will get pretty tedious. I'd prefer it if I can make a function that takes the letter and the number as arguments. So, if it gets the arguments "E" and "10" it will perform the operation on variable E10. What is the syntax for this? say a simple operation such as: result = E10 * 3 Is the syntax any different if I use constants instead of variables?
