Here is my case:I have a richtextbox called Rtb1 I have the text property for this control set to "ThreadAmountEdit=[Thread Amount]" This was set through the RichTextBox Tasks function, by clicking the control and selecting the little arrow in the top right corner. In working on my form, I edit the text "[Thread Amount]" of the rich text box to "45". What I need is to be able to reset Rtb1 back to default ("ThreadAmountEdit=[Thread Amount]")on button click.

I've tried: Rtb1.Refresh() which doesn't appear to do anything I've also tried Rtb1.ResetText() which completely clears the textbox.

Get Amount Of Money User Has And Doesnt Go Over Amount Hechecked

Jun 7, 2011

im trying to make a fast food program on which the user will input the amount that he has, then he will check on what he wants, by using check boxes. There are 7 different check boxes with 7 different amounts of money. I have the program somewhat finished (thanks for the people that helped me before) but theres still a couple of things that I still need to get finished but I dont know how to.I need to be able to get how much money the user has (this will be entered threw a text box, I think I accidentally messed this part up, because I cant get it to work right, (theres alreasy a permit amount of money in there and it needs to be what the user enters instead of the permit, 5.59, one) and this will be the maximum amount he can spend, then the user will check on the food he wants (and the program will add the sales tax also) then it will produce an answer saying if you have enough money or if you dont. But what im confused on is how do I get the users amount of money and make it the maximum mount he can spend and make sure it doesnt go over the amount that he has checked.[code]

Reset Button To Reset Player

May 29, 2009

Ok, so I am building my own program to control a video player I have through telnet, I have everything else working except one thing.I have a reset button to reset the player, when I press it, it sends the string "Reset" and the unit resets without a problem.But when I add a code to close the winsock connection upon reset, it doesn't send the string to the unit. I am sure what is happening is the winsock is getting closed at the exact same time it is trying to send the string and so it fails to send, how do I make it close winsock AFTER the string has been sent?

Payroll Calculator - Program Must Calculate And Display The Total Pay In The Total Pay Label

Oct 6, 2010

The pay rates for the project are:

a. Level 1 - $10.00
b. Level 2 - $12.00
c. Level 3 - $14.00
d. Level 4 - $16.00
e. Benefit Deduction Rate - 0.10
f. Overtime Factor - 1.5

For ease of program maintenance, all of the above rates and factors must be stored in module level constants. All references to pay rates in the program must refer to the module level constants.

When the Calculate button is clicked:

a. The value in the Hours text box must be validated to insure that it is numeric value greater than zero.

1. If the value is not valid, a message box must appear as shown below and the user must be offered the option to continue processing or quit the program.

2. If the user chooses to continue processing, the focus must be set to the Hours text box.

3. If the user chooses to quit, the program must close immediately.

b. If the value is valid, the program must calculate and display the total pay in the Total Pay label.

1. The pay rate is determined by which Job Grade radio button is checked.

2. For hours less than or equal to 40, the total pay is the hours times the pay rate.

3. For hours greater than 40, the total pay is 40 hours times the pay rate plus the hours in excess of 40 hours times the pay rate times the Overtime Factor.

4. If the Full Time radio button is selected, the total pay must be reduced by the Benefit Deduction Rate.

5. The value displayed in the Total Pay label must be formatted with a dollar sign and with two decimal
places.

6. The focus must be set to the Hours text box.

Why i get an error when i try to run this code

Code:

Also the message box, both yes and no close the program.....

Loop Through Top Level Folder In Mapped Drive And Give Total Count Of Files And Total?

Oct 28, 2008

I am working with VB 2008. I want to be able to run this program say in N: and it will show me in an excel sheet the following:

Folder Path Size(GB) Count of Files
N:Clients 0.53 308

where clients contains subfolders and files and the size is the total of all those files within each folder and the count is the total within each folder also.

This works fine as it is but i have to select one by one the top level folders and some of them are huge so it takes forever to give me an answer.

1) I would like to see in my spreadsheet the following by only select the network drive n:

Folder Path Size(GB) Count of Files
N:Clients 0.53 308
N:Software 10.7 15430
N:Billing 0.98 105

2) I would also like to know if this is the faster method.

3) I tried adding a progress bar so that the user can have an idea of how much this will take but i had to remove because it was not working.

4) I would like to see the folder name, size of folder and count of files in the listview.

Here is the code:

Imports Microsoft
Imports Microsoft.Win32
Imports Microsoft.Win32.Registry
Imports System.Collections

Adding Another Total To An Existing Total?

Nov 21, 2009

I'm new to forums as well as new to VB 2008. I'm in process of making a order calculator which will total any values you selected in combo boxes/checkboxes and then display it in a selected area. There are 3 things that I want to achieve: 1. Be able to add another total to an existing total (currently I'm able to see only one total when I hit "Calculate" button)2. Display how many orders I have made so far (new total counts as one order)3. Be able to add up checkboxes selected to an overall total. (when I try to add up one checkbox with another it seems to be stuck on 1.5 pounds which I assigned for each "side order")

Assigning Values To Cards?

Apr 27, 2009

basically i've gotten myself into a mess with some last minute project work. shame on me and all that but thats college students for ya. basically i seem to be having problems assiging a simple integer to some pictures in an array. now. basically its a card deck. i've looked this up so many times yet nothing comes to me that fits my code or the way i've been taught. in any case i've got an imagelist and put it into an array to symbolize a deck. now. as i'm doing blackjack i need each card to have its own value. so obviously 2 of hearts value = 2, king = 10 etc.so what i've done is created a function that calls on a string. and used a select case to give a value based on the filepath of the image. however it failed hoplessly. heres a piece of the code:

Sub getcardvalues(ByVal card As String)
Select Case card
Case "decklist.images.item(2club.png)"
value = 2

[code]....

despite this seemingly simple solution i can't seem to pull out the path of these cards as a string. the array simply gives me a number and the actual picture dosnt want to be a string. so my question is this. how can i pull the image path out of the array (eg: deck(1) = decklist.images.item(3club.png)) and turn that into a useable string?
