VS 2008 Using Loop Variable As Array Selection?

Oct 10, 2009

Lets say I have declared an array by doing:

dim array()

Also have a variable:

dim loopsize = 10

Then i do this:

for loop = 1 to loopsize
array(loop) = 5
next

What i wanted to do with this is from array(1) through to array(10), the values will be changed to 5. But vb will not allow this and crashes.

Why doesn't this work and how can i make it work?

Saving New Selection From Combobox To SQL Database?

Jun 17, 2010

I have an app I'm working on with multiple forms. One of the forms, frmLocationInfo, has textboxes and comboboxes which are automatically populated based on a combobox selection from a previous form, frmLocations. I've been able to get any changes made to frmLocationInfo's textboxes to save to the SQL database, however, when attempting to select a different item from any of its comboboxes, it's not saving to the database and instead, I receive a "Procedure or function...has too many arguments specified" error.

Here is the code for the Save button:
'Save changes to Locations db
Private Sub btnSaveClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)

VS 2008 - Storing Selected Item In ComboBox To Variable On Button Click

May 10, 2010

I have 13 variables, all called Items1, Items2, Items3 and so on. I have a combo box with items in, each time I click a button I want it so whatever is selected is stored in a variable and if the button is selected again then it stores whatever is selected in the next variable. I know all the code for selecting items in a combo box and transferring it to a variable but the problem I cannot do is the part where each time a button is clicked it stores whatever is selected in the combo box to the next variable.

Runtime Variable Field Selection In Code Behind?

Jan 23, 2012

I have a list with several fields that is created from dataset from a linqtosql query. At run-time, the user gets to specify what field he/she wants to display from the list. In other languages, I can dynamically do this like:

valueIwant=mylist(i).[fieldnameImInterestedIn]

Where 'fieldnameImInterstedIn is itself a variable. How do I do this in VB.Net?

non-working actual code follows:

Dim patientdata = (From patientvar In pdfdatacontext.tbPatients Where patientvar.PatientID = patientid)
Dim patientlist = patientdata.ToList()
fieldvalue=patientlist(0).(reportrow.userselectedfieldname)

Forms :: Move Selection Highlight (in E.g. A List, Grid..) Upon Right Click?

Sep 16, 2006

When we left click a grid cell, or list item, it highlights. Left click outside it and the selection jumps to the new place.

I can RIGHT click anywhere in the grid without disturbing an existing highlight, but I want it to work more like windows explorer would in terms of file selection..

i.e. if I right click inside the range, the range stays, if I right click outside the range, the range moves to a new single cell that I just right flicked.

Try it now on this page. Select some text, right click on the selection and it stays. Right click outside the selection and it goes. In datagrid (for example), the selection can only be modified with a left click.

How can we change this so the selection behaviour of a datagrid/list is more like this text pane?

On a related note. If I left click in a textbox I can drag a selection out. If i wanted to right click and drag the selection out, would it be the same process? (It's for a custom string manipulation picker control..)

Saving Variable Between Uses?

Oct 27, 2009

I have written all that is required at this point and have published the program. I thought that global variables were saved when the program terminated but, as I found out, they aren't. If anyone has any way of making the variables keep their values between uses of the program I would be very grateful as if the program is being run for the first time some global variables need to be set straight away (I have done this code). The variable types are: one boolean and a few strings.

Saving Changed Data Before DataViewGrid Selection (Row) Changed?

Jan 20, 2010

on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?

Saving Mouse Coordinates At Click?

Feb 22, 2009

I need to create a program which can press anywhere on the computer screen. I need to click once with the mouse, and then save those coordinates, and afterwards the program self press the mouse at the point. It needs to be an application - not an applet. I have read something about MouseEvent, but I cannot quite figure it out, how to get those coordinates. Currently I can create a program with presses at some coordinates I self gives values as points in the source, I did that with the Robot class.

VS 2005 Saving Battery Level Variable To Text File?

Jul 28, 2010

Currently, I've encountered a problem where I do not how I can store the variable of my battery level in a text file. I tried .xml and .txt file and it returns me text which can't be read.The code related:

vb.net
[code]Dim psBattery As PowerStatus = SystemInformation.PowerStatus
Dim perFull As Single = psBattery.BatteryLifePercent

[code]....

The place where I do not know what to insert is the "Insert Battery Percentage Here" part so I guess that's the problem.For your info, if you were to use a MsgBox to display, the code which displays that would be <MsgBox("Total battery power remaining: " & perFull * 100 & "%")>

.net - ASP.NET Session Variable Is Wrong After Multiple Click Event Fast?

Feb 29, 2012

I have an asp.net website to manage projects. I realized that when I click for the next project really fast and often it overrides all the next projects with the data of the first one. I call a method to save before to go for the next project. I use also a session variable for the id of the project.

EDIT: It looks like the sever stacks the save method and the ids but keeps the values of the first project in the controls this is the ajax that calls a server method to get the id and set it in an hidden field:
