(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?

I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?

I've been literally googling for an hour now trying to find how to save variable settings to a file.I'm writing an application and I'm using alot of changeable variables. I want to be able to save these to a file so they can be loaded at application startup. I don't feel like using the regestry since I hate to write unimportant things to the registry.I remembered that I found a good example with simple code of how to do this with xml, but I can't seem to find the example now.

I have a DEM file(Digital Elevattion Model File) and I am trying to open the file,where we have Latitude and Longitude values inside the DEM file.And, Now I have opened the file using Filestream and Read the file using BinaryReader.But, I am having a trobule in getting the values of Latitude and Longitude.I am getting Byte values randomly as 1,202,31,271 etc.But, we dont have latitude and longitude values more than 180,and also I am not getting 16 bit UInt values.For example, the values should be like Latitude 20.00416666666667 and Longitude 39.99583333333333.So,read the correct Byte values of the DEM file.The code I have used till now is:
Dim fs As FileStream = New FileStream("C:UsersadminDesktopHeader and DEM fileE020N40.DEM", FileMode.Open, FileAccess.Read)
Dim rd As New BinaryReader(fs)
Dim convertDB As UInt16
For i = 0 To rd.BaseStream.Length

I have to design a project for my IT course at college using Visual Basic. The task is to create a program which allows the user to enter the height of a room plus the width of the walls as well as the paint which costs different prices. I have managed to get the program to work out the cost of painting each wall, but I cannot get another label to show the price for painting a full room, when the result is basically adding up the cost of painting all of the walls. how to add up multiple values displayed in labels?

so i have this code which is trying to allow the user click the label (of which there are 26) and then decide whether the letter in the label matches the letter that has been generated in the radio button. I KNOW there is a more simplified to do this and much less code to write but i cant work it out. this is an image of what im trying to achieve but instead of buttons change those to radio buttons x 3.

I want to get a matricial data (a matrix of numbers, like a txt data with TAB separators) from the clipboard and put these numbers each one in many Labels (or other Control that would be easier to work with numbers - maybe NumericUpDown, but I don't like his look). I don't know how to Declare, Define, or anything.... I just want to click on a button and then get the data from the clipboard, check if it's a number (or matrix, or whatever).... and put one by one in each Control (label) that I want.For example:
I have in the notepad the follow:
1 "TAB" 2 "TAB" 3 "TAB" 4 "ENTER" 5 "TAB" 6 "TAB" 7 "TAB" 8 .. end
like a matrix {1,2,3,4 ; 5,6,7,8}
If I just copy it to clipboard, it will be copied like a matrix, right?? So, what is the command that I have to use in VB that catch this data and bring to my program (clipboard.getdata would be the more correct?)And then, when I alredy have catch this data, how can I put the number 1 in the label1, number 2 in the label2, number 3 in the label3 and so on..Remember that I interested in use this numbers to calculate other values after and present the results in other place, and I know (maybe wrong) that labels is not the more apropriate Control to work with numbers?

I have designed a program that, when the "caclulate" button (btnCalc) is pressed, it asks the user for a file name, then pulls data from that file (file is a .txt of 100 decimals, one per line) and displays the Total, Average, Highest and Lowest. To do this, I have placed all the data into an array, and then used the array to get the information I need. All the code is in place, the only issue is that when the "calculate" button is pressed and the file name is entered, nothing happens.Need to figure out why the values are not displaying in my 4 labels (lblTotal, lblAverage, lblHighest, lblLowest)!!Here is the code:
Imports
System.IO
Public
[code]....
(For the record, I know I could get the data in one pass, however, being a beginner, I like seeing each value computed separately.)

I am looking for a way to save and load the values of all my controls present in my form.My form has around 100 controls spread over 7 tabs. The controls include (Multiline) TextBoxes (Strings), NumericUpDowns (Integers, Decimals) and Checkboxes (Booleans). If the user clicks the save button a "Save File" dialog should appear allowing the user to specify the directory and the filename of the save file.All the values of the controls should then be written to that file.If the user clicks the load button an "Open File" should appear where the user can pick a previously saved save file. All the controls should then adopt the values found in the save file.I have implemented Application Settings in my form, and now when I click save, it saves the control values through My.Settings.Save(). If I click load it loads them.However, my project requires that multiple save files can be made to reflect multiple configurations. As I understand Application Settings only allow for a single .config file in the Application Data folder.So how can I code a save/load routine to save/load different configurations?

I'm trying to make a program that allows the user to click on labels which have a number in it and then that value has to be stored into a different label.
For example the user click on label1 and the values goes into label12, then it click on label3 and the values goes to label13 and so on.
At the moment I can only code on the respective label underneath (1->12,2->13...) but it has to be in any order (5->12,7->13...)
Here a picture and below my code:

I have to save the text boxe values of a form to a text file almost like a data record. I will be saving an Employee First Name, Last Name, Dept Number, and Phone Number. This I know how to do using streamwriter.
next form which we have to use stream reader to load one record at a time. The form has a next button to load the next record. How do I seperate each record (I am sorry for calling it a record if this is inappropriate) when use streamreader and how do I load a record at a time.
I know how to open a file and use streamreader, I just don't know how to read one record at a time and move to the next one.

I have an MDI parent screen that loads on startup and a lot of child forms that load when opening. So as the child forms load there's a lot of flashing and it looks really ugly. Once they're loaded all I have to do is use a bring to front, maximized command and it works smoother than closing a form and opening a new one every time a different form is selected. I've tried creating a splash screen, minimizing the forms on load, etc and everything still works in order so first the splash screen then the forms load.
How would you set it up so a splash screen stays on top of all other forms for like 5 seconds while the forms load in the background without seeing them load? Right now the screen shows then when it's done it moves on to step 2 which is loading the child forms. If no splash screen, how do I make it load so you don't see all the child forms opening at once?

I'm a "Moderate" skill programmer, and am upgrading some software I've written in VB.Net (VS2008, .Net 3.5), and need to be able to accomplish the following, which I'm not sure of the best way to go about doing: The software is an information reporting dashboard for a call centre. I have a csv file being created about every 10 seconds, extracted from the telephone software, the file consists of a list of "Skills" (basically telephone line types), the number of calls received on those lines, and the number of callers who hung up (and a few other bits of information I need, but once I figure the basics out, the rest should be easy), basically looking like the following:
[code]...
I need to be able to read this csv, store the data, filter out the "Skills" to be report on (i.e. 1,2, and 5 only), add up the "Offered" and "abandoned" data associated with them and then display this information as one number (i.e. "Skills 1,2,5 - Offered: 4925, Abandoned: 13") (and then the same for the other "Skills"). This data could grow as more phone lines are added or some are taken away.I've got the code to read the data into an array working, but I've got stuck with how to filter and add up the data. I'm not even sure if I can do this with an array.

I have a P/L chart which has a left scale (Y axis) which starts from a negative value. I want to format the axis labels (the major tick mark labels) so that the negative ones are red.
Something like;
If cht.ChartAreas(chtarea).AxisX.MajorTickMark.Value < 0 Then
cht.ChartAreas(chtarea).AxisY.LabelStyle.Font = New Font("Verdana", 9.0F, FontStyle.Bold, Color.Red)
[Code]....
Of course that doesn't work since MajorTickMark doesn't have a value property. How does one make this work?

I've bound a lot of controls on a form to a Entity. Some of them update fine, the others are just jumping back to their original value as soon as it loses focus.The old data are loaded in all controls perfectly.
Dim Q = From e In EnData.Calls Where e.CallID = ID
TempRow = Q.FirstOrDefault()
ticTemp1.DataBindings.Add("Value", TempRow, "CallDate")
ticTemp2.DataBindings.Add("Value", TempRow, "CustomerID")
How can this be fixed?

I have a form with a couple of multi-line text boxes, a couple of radio buttons, and a couple of check boxes. When the form is closed I need to save the values of the textboxes, radiobuttons and checkboxes so their values will be retained next time the form is open. I've done this in VB6 on form open and form close, but I cannot get the same module to work in .NET
Here was what I used in 6.0 to save:
Sub SaveFormState(ByVal SourceForm As Form)
Dim A As Long ' general purpose
Dim B As Long
Dim C As Long
Dim FileName As String ' where to save to
