Changing Unknown Number Of Label Captions Using Unknown Length Array

Oct 22, 2009

Using Access 2003 and VB code, I have created a form with a number of labels. The labels will display an employee's names. I have named the labels name1, name2, name3...etc. Using an ADO data set and DCount I have determined the number of names in an Access table (the number of names can vary). What I want to do is for each record in succession to pick the first name and surname from the data set , combine them into a full name (this part has been successful), and then set the full name into the label caption in succession. Example: full name 1 into name1, full name 2 into name2, full name 3 into name3... until all names appear as labels on the form.

I created a counter to and a variable to increment the label number but when I address the caption property of the variable containing the new label (e.g. name1, name2..etc.) it throws an errer at runtime. Here is the code:

Storing Data With Unknown Length In Array

Jan 15, 2010

I have a piece of code written in Visual Basic:

Dim n As Double, i As Integer
n = 4
Dim Ramp_length(1 To 4) As Double
For i = 1 To n
Ramp_length(i) = Cells(13 + i, 5)
'Cells(65 + i, 7) = Ramp_length(i)'
Next i

Is there a way I can reproduce the result without declaring the array with a "fixed" length? I eventually want the code to read off a column of data with unknown length and store it in an array of equal or smaller length so it can be altered.

Nov 10, 2011

I'm developing a program at the moment and I'm trying to add the capability to add a texbox everytime you click a button. This is simple other than I'm trying to be efficiant as possible, so I made a sub that creates the textbox and the button calls the sub. Here is where it gets tricky I want the new textbox to move just below the previouse textbox, I'm not sure how to do this since Im only really createing one textbox over and over and having a variable name it by one. This souds confusing I know, but check out my code and it will make since. Really all I'm trying to do is change the location of a unknown textbox say since I create a textbox name textbox0 then when I hit the button again my varibale goes up by 1 which makes the new textbox, textbox1. how to I tell VB to change textbox1's location....

Enum ToString Returns An Unknown Number?

Jul 16, 2009

I built a simple vb.net winforms project that pings IP addresses and logs the results. It works fine on most machines I've tried it on. I log the status result of the ping System.Net.NetworkInformation.IPStatus) by using the IPStatus.tostring method.

Normally this returns a text result such as "Success" or "TimedOut"Yesterday, on one machine it returned "65" ...which is not one of the enum values. I have a feeling it might be a combination of values. I ran some test code:

Dim status As System.Net.NetworkInformation.IPStatus
status = Net.NetworkInformation.IPStatus.Success
MsgBox(status.ToString)
Which returns "Success"And this: status = Net.NetworkInformation.IPStatus.BadDestination Or Net.NetworkInformation.IPStatus.BadHeader MsgBox(status.ToString)

Which returns "11050" I suspect the "65" I saw was the result of some combination of enum values. Is there any way I can change the code in my second example to show the text names of both values? That is... any way I can see ALL values in this variable?

Sql - LINQ Or DataTable When Number Of Fields Unknown

Feb 25, 2010

I have a dynamic query which returns a DataTable. This DataTable will contain a varying number of columns depending on the selection used in the query. I want an efficient way of filtering the records in the DataTable.

For Example The DataTable contains columns : A, B, C and D

I need to query this data at serveral points in my program. At some point I may need records where A=10 and C>40. At another point I may need records where A<10 and D=90 etc.etc. The selects are dymanmic, I do not now what Columns or values are needed until the code is executing.

I could simply use a DataTable Filter and build the selection string dynamically. I have no problem with this. However I was wondering if using LINQ would be more applicable. I am completely new to LINQ and would like to use it but don't know its capabilities.

(At present I am using a DataTable but in future this may change to a collection of Objects)

VS 2010 - How To Add Unknown Number Of Items To ListView

Mar 14, 2010

I'm gonna add x number of items to a listbox in form #2 form form #1. When I click the button it opens Form #2 and then I tried this code (which makes the form freeze):
Dim qwe As Integer = 1
Do Until qwe = regKey.GetValue("Count") + 1
PrMaker.ListView1.Items.Add(regKey.GetValue(qwe))
qwe = qwe + 1
Loop
The regKey.GetValue("Count") is a registry key which contains a integer (unknown). What is wrong, or is there another, better way, of doing this?

Pretty straightforward...

instead of nominating a specific form (myform) I want to leave it open at design time[code]...

Browsing And Selecting Unknown Tables

Mar 12, 2009

I am trying to load some data from a database table into a data grid. However the way it is accomplished is that the user will be able to select the database (i.e. the database can be located anywhere in the hard drive) and once he or she selects the database, a second interface would allow him or her to select the number of tables within that database (can be any number of tables). Once the table is selected the contents of the table will be loaded into the datagrid. It is just like opening an Access (.mdb) file and then click and open a table within the file except that it is done programatically

Copy An Object Of An Unknown Type?

Jul 29, 2010

Rather than giving the very specific case (which I did earlier), let me give a general example. Let's say that I have a function, called callingFunction. It has one parameter, called parameter. Parameter is of an unknown type. Let us then say that I wish to copy this parameter, and return it as a new object. For example, in pseudo code, something along the lines of...

[Code]...

EDIT: Additional Information The first time I posted this question, I received only one response - I felt that perhaps I made the question too specific. I guess I will explain more, I have an ASP page with 10 tables on it. I am trying, using the VB code behind, to come up with a single solution to add new rows to any table. When the user clicks a button, a generic "add row" function should be called.

The difficulty lies in the fact that I have no guarantee of the contents of any table. A new row will have the same contents as the row above it, but given that there are 10 tables, 1 row could contain any number of objects - text boxes, check boxes, etc. So I want to create a generic object, make it of the same type as the row above it, then add it to a new cell, then to a new row, then to the table.

Focusing Window With Unknown Title?

Mar 27, 2012

I'm trying to focus and bring a window with an unknown caption/title to the front. The window is in a clinical application that we use, so I don't think there's any way I can do it inside the framework, as we get this application from a vendor. The window will always start with "Member - ". I have code below that I have used in the past to find a window and focus it when I know exactly what the title is.. but in this case I don't know what the title is. Does anyone know of another API call that I can use to search through all windows and compare their titles as text to see if any of them match the text I'm trying to compare with?
