Add Numerous Variables Together To Display In Another Textbox?
Jan 14, 2010
i'm having is I have a 4 comboboxes with values connected to the items. I have textboxes set up so the values of the items show up. The items are concatenated ("" & processor(0))The processor variable contains the number, so how would I add numerous variables together to display in another textbox.
I am writing a program that will display numerous labels in English and Spanish. The problem is I have the formatting correct and labels aligned for English, but when I hit the button for Spanish the labels on the left overlap the labels on the right. I did set the text on the Spanish side to include 10 spaces before the text, which does align it properly, however there has to be a better way to do it. I tried padding the label on the form which works good, but I would like the padding to only take effect when the selected language is Spanish. Once English is selected I would like the formattting to go back to normal.
I have numerous textboxes which I use to gather data to be placed into an array. But I want to ensure, before I place them to the array,that there is at least one character (letter or number, no space) in each textbox. Seeing as I have about two dozen, it would seem tedious to write an If...Then statement for each of them. And I cannot use a custom textbox class for this. So how can this be done?
I need a way to add hundreds of thousands, millions, and possibly a billion items (Really anything in the range of Int32) to a DataGridView Control quickly, I was hoping for something under a minute. I have been trying various ways, the fastest way so far I have found is to add cells to a DataGridViewRow and then add the row to the DataGridView Control. As of now, I am using a BackgroundWorker as a second thread so I show progress of the operation.
I have the following macro that will find a word in a document, then 'bold and cap' it. If I want to find 50 words in the document and do the same thing, I can just copy the macro 50 times. Is there an easer way to do this?
Set SearchRange = ActiveDocument.Range With SearchRange.Find .Text = "My Word"
I'm trying to set multiple variables using a textbox.The way I'm trying to do it is have each variable seperated by a space so like this:#If textbox1.text.contains("test") then set variables from textbox1.text for each " " in textbox1.text define new variable(value, string1, string2, int1, int2, int3, int4, int5)#End If I just don't know how I would code something that can set these variables from a single line of text in a textbox seperated by nothing other than just spaces.
I have some code where I am trying to use variables in a tabpage. The first tabpage only has one text box for user entry (miles.text) and a button to do a calculation: traveltime = mileage/speed. The value from miles.text is stored into a variable called mileage while the speed used is stored in a variable called speed (me.speedtextbox.text).
Ordinarily, doing val(variable.text) works like a charm and it's not doing it in this case. When the user enters 100 for the mileage, it should be divided by 65 (the number in the database) and, therefore, the answer should be 1.53 hours. In my case, I'm getting "infinity" and whenever I do anything else with the variable, I get "when casting from a number, the value must be a number less than infinity." But it is! It's only 65 and I double-checked that the dataset said that too, which it does. Not sure why I am getting this error.
I have a database I am creating with about 50 users over a network. There are about 6 groups of users and these users are spread across 10 branches. I want to block/allow users from particular forms and views. For example I want branch users forms to be filtered by their branch number but depending on the group they are in they can only see some forms. i.e. 50 users, 10 branches, each branch has about 5 ppl of where 1 is in group A and 4 are in group B. I want all users that belong to branch 1 to see the information they enter, but Group B enter data but cannot approved or delete, and group A can enter, approve and delete. So then. On my login form I have the user type his/her username but the i want LEAVE function to update 2 textbox where I have named GroupName and BranchNo. Basically to run a query and look for the username and return in one textbox that user's groupname and the other textbox the user's branch no. This information will be used to filter forms and block the user from certain controls. This is the code I have so far but still can't figure how to display the results.
Private Sub UsernameTextBox_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles UsernameTextBox.Leave 'Make Connection to database
[Code].....
It keeps highlighting the BranchNumber and UserGroup and giving error "Value of type 'String' cannot be converted to System.Data.OledbCommand
I'm facing a problem with my current member card reader development.
I'm reading the card number (just a serial number of 4 digits) with a card reader. this seems to work fine (even converting the text string to integers).
This number is then put in a query to find the exact record that corresponds with this number
I recieved a gift recently visual studio 2010 ultimate a nice suprise I have been repairing and building PC's and networks for years working in local shops and buisnesses, but always wanted to learn programming so my GF purchased this for me nice suprise. So here is my beginner question. I am making a program that will take check info ( check number, amount, date and person or buisness wrote to). I have no plans on using it just trying to learn variable structures and arrays and thought this type of program was a good start. Now I would like to take the text of a text box in runtime and use that to input a new check number into the variable structure. Just so I am not confusing anyone I will write the basic code
[Code]....
So what I would like to do is use a textox labeled check number to add check numbers into the checkrecord structure instead of having to add them into the code manually is this possible?
I have a form with a few text boxes, one of which has it's contents stored to a integer variable.
The value stored will end up being one of a few numbers ranging from 12 to 98, and I need to the same number of new variables as the number in the textbox.
Can I automate the creation of new variables based on the value stored, or do I need to define the max number required and just ignore the rest when using less?
I made a simple textbox with a submit button and a label and when you type in something into the textbox and hit the submit button what ever you typed in the submit button is suppose to show up in the label box but i type in DaFallenAngel in it and it only shows D why is it only showing D and not the full name? [code]
I have 10 forms and say 5 text box's on each one so a total of 50 of these text box's. But the program is only using one of these forms only (user selects the 1 Form out of the 10) so I was wondering can these forms Share the input text box's? I am thinking NO, if so then the only thing I can do is just use 5 shared variables that all the forms can utilize.
I want a rich text box to display public variables like (pizza toppings links etc that have been selected in other forms) these variables have declare in a module. But I want the rich text box to display these variables as soon as the screen loads ( a on form load event) if you know what I mean.
Last year (2010) I came across a FANTASTIC command that allowed me to take a string of variables with a common delimiter and break it all back out into separate variables (possibly an array) with one statement.
[Code]...
As long as the delimiter was a unique specifiable character, this one-statement command could break it out into elements. my memory and point me in the right direction.
I have code, shown below, that works all except for 1 thing: The variables being passed byRef get passed, but once modified in the else section of the "if me.invokerequired" code of RecordData, the variables are never updated in the calling function. To reiterate, the calling function does not receive the updated data that is in the variables custid and amt.When debugging, I see the data change in the else section of "if me.invokerequired", but once it returns from the callback the data is missing.[code]
I define some global variables of a class as follows:
Private Class MyClass Private var1 as Decimal Private list1 as List(Of string)[code].....
But I found that after this form is closed, all above variables, var1, list1, list2 still exist in memory. I thought they should be collected by gc since the form is already disposed as I confirmed.
Add: I have monitored half an hour after the form is closed. But these variables are not collected by gc. I have an automatic update procedure on the form which uses above variables.Since the above variables still hold values, the automatic update procedure is always called which causes exception. (One quick fix is to check if form.isDisposed in update procedure. But I do not think this is elegeant. Besides, these variables occupy memory.)
Does the memory used in declaring variables are reclaimed by the OS when these variables go out of scope?Does the memory used be released by setting thier value to nothing? if not, then how can I force the garbage collector to run or excecute at a certain/desired time..How about in Windows Forms..How can we make sure that the memory used in initializing and showing forms be released if those forms were closed?
Question 1: What is the difference between "Background Worker" and "Worker Pool" as indicated within the MSDN samples provided.
Question 2: I noticed while using, AddressOf _Function_, variables cannot be passed; what would be an efficient solution to this?
Question 3: While using multithreading is it required to invoke before setting variables, or only form properties?
Question 4: While using System.Net.Sockets is it safe/efficient to use Application.DoEvents while waiting for new data; or would be using a Do While loop be fine without DoEvents since the action would be multithreaded? Note: there can be up to 2000-3000 sockets in use at a time.

I am making an application which will have a member list for my clan (with listbox), and times of warnings (with label), and conflicts people have had with this member (listbox).I want my application able to add members (with saving in file), and remove members (with saving in file), and remove warnings (wth saving in file).As I dont know how to split and remove and store stuff in a single file, it'd be impossible for me to code. That's why I come here and ask if someone can code this for me.Some of my friends said it could be possible by splitting each line, in the following format in a .ini (doesn't have to be .ini it can be also a non-format file) file:
This friend can't help me now, because he suddenly had to go offline, he might not come online today aswell.I have already made the interface, but as I said before, I have no idea how to code this and would like some help with this application.All the members I would like to store in: lstMembers (Listbox All the conflicts per SELECTED member I would like to store in: lstConflicts (Listbox)The warnings per SELECTED member, I would like to store in: lblWarningI want to know if this is all possible and HOW, since I have no idea what Split can do.
