How To Set Some Of Correct Values

Apr 17, 2012

My VB code uses a timer with a slider, and uses AddSeconds. I am trying to use the slider with a min value of 0 and max value of 600, and set up ticks every 30 seconds between 0 and 600.At a beginner level coding VB,I am not sure how to set some of the correct values in the slider's property box.Min, Max and Value, I am guessing are 0, 600 and 0 (sets the slider thumb starting positionat the far left). But I am not sure what other values, like tick and small and large change, etc. need to be set and set to what value? I've read online, but so far cannot find how to configure this.

Textboxes Not Displaying Correct Record Values?

Nov 29, 2011

I got 100+ textboxes that display record values. Most of the textboxes display correct values but several textboxes doesn't. These are the same textboxes. And they only display wrong values if I edit a record for the first time. After correcting the wrong values in the textboxes the first time, they display correct values in succeeding editing of records. Tried to compare their properties and all but they are the same with textboxes that worked...

Sql - Configuration File For .net (Unable To Pass In Correct Values)

Aug 30, 2011

An exert from my config file looks liek this.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>

[Code].....

EDIT: I am able to pass in the string perfectly when using Visual Studio 2005. But when using VS 2003 and a loiwer .net framework it will not let me, unless I hard code it in.

Could something be enabled/disabled on one of these instances of VS? Or could this just be an error with the older versions of .net? I think I am using 1.1??(will have to check) in 2003.

VS 2005 Getting The Correct Number Of Attributes To Match The Correct Number Of Text Boxes?

Apr 18, 2009

I have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code

Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)

[code]....

The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.

How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)

Get A Handle On The Correct Way?

Jul 2, 2009

I am trying to get a handle on the correct way and easiest way to do things. By easiest I am not talking about being lazy just accessing and modifying later on. I have started using my own classes and such but I have a few questions. Sometimes I want to create a control on the fly through code instead of using the designer. Should I create this control in the main form file or in a separate class? If I make it in another class it seems harder to access later on. Then again if I dont know that the control is going to be created(user clicks a button to add a control) how can I access it? Also it seems alot harder to access certain things when it is in another class. For example if I create a new window in a class and then want to check if it is there or not it is alot harder to do.

Dim rd As New BinaryReader(fs)
Dim convertDB As UInt16

(VB2010) Save The Values To A File Which Loads The Values In The Specified Labels On Startup?

Jun 2, 2011

lets say I have a form (form1) with lables a-z which are all designed with default text "0". So they all show 0 on program startup. which is fine. I also have a dialog with 2 TextBoxes; I want my program to update the default text/value on (only)form1 labels x, y and z to whatever was put into the textboxes when i press the OK button on the Dialog, so these specified labels show the 'new' value on next startup. Is it even possible or should I save the values to a file which loads the values in the specified labels on startup?

Exclude Multiple Values In Sum Depending On Values In 2 Columns In SSRS 2005?

Apr 21, 2009

I have simple columns and their respective sums. However, I exclude 1 particular value from each sum, like so [code]...

Now I need to exclude another value ("Awaiting Progression") from a second column called "PROGRESSION".

Since I already exclude value based on 1 column called CATEGORY, how do I change my =Sum(Code.ExcludeOthers(Fields!CATEGORY.Value,Fields!ACTION_PLAN_NEW.Value)) to exclude a value from the PROGRESSION column if it's = ("Awaiting Progression") ?

i.e. How do I exclude multiple values, depending on values in 2 columns in SSRS 2005?

C# - ComputerInfo.TotalVirtualMemory Is Not Correct

Oct 2, 2009

I have a question about the property TotalVirtualMemory in the VB class ComputerInfo. I have checked this property from code on several different computers and the number is always 2047 MB. This is strange because I know for a fact that the virtual memory on these computers differ (~1GB, ~2GB and ~3.5GB). Does anyone know why it is like this and is there any other way to get the total and available virtual memory?

Correct Method For Resize?

Jul 15, 2009

I use vb.net 2008 to create a desktop application.I have a form that is resized according to the size/location of the app bar (where the start button is)I have a toolbar at the top, a status bar at the bottom of the form and a grid in the middle of the form I want the size of the grid to be the maximum possible on my form.if and when the user resize his application bar (or move it from the bottom to one of the sides) my form size should change according to the new working area size:

H = My.Computer.Screen.WorkingArea.Height
W = My.Computer.Screen.WorkingArea.Width

is there a single event that I can use ? currently I called my resize function in several form events: Activated, ClientSizeChanged, Load,Paint,LocationChanged,RegionChanged.And still it is not working correctly! Resize the app bar size or move it form does not change !

If I minimize it and then display it again or click it - it changes size
