Compare Text In A TextBox To Values In A ComboBox ?
May 10, 2009
Again a little (for me) tricky thing:Supose you have a ComboBox control with predefined values - to keep it simple, let's add some colors:
- Blue
- Green
- Red
- Yellow
Now you have a TextBox control as well. If you type into the TextBox BLUE (non-key sensitive) I would like to make it recognize that this value already exists. It does not have to do anything else except for notifying me about a match.I do think that the TextBox1.KeyPress or TextBox1.TextChanged event is what I need but I have no idea how to compare to the ComboBox1 items. I've tried to create an Array of my ComboBox1.Items but didn't get much more than errors. Can anybody help? I am sure it is quite simple however, I can't get my mind set to go in the right direction

Basically i have 12-16 text boxes, with certain values in them.
i think i need a nested loop one to take first box and go through the rest to compare them and then a second loop withint that to do the actual comparison.

For example, if I have two text boxes, I want to compare the numbers in each to see which is higher and then commit actions if one if higher.

First I create a class which have a string property
Property stdName() As String
Then I open a text file and put into array of that class
Dim arrStudent() As Students
Dim allstdinfo As New IO.StreamReader(dlgOpenStudentsFile.FileName)
Do Until (allstdinfo.Peek() = -1)
Dim strAllstdinfo As String = allstdinfo.ReadLine()
Dim arrStudentLine() As String
[Code] .....
Finally I run a for loop and compare the stdName property with textbox.text
Dim counter As Integer = arrStudent.Length
(debug here)
For i As Integer = 0 To counter - 1
If (String.Compare(arrStudent(i).stdName, txtStdName.Text) = 0) Then
lblPhoneNo.Text = arrStudent(i).phoneNo
End If
Next
And I add watch:
Why the compare return 1

I've build a list of Strings from files. The list itself is working fine (tried it by having ListBoxes and other controls loading its items from there just to make sure that this is not the issue). Now, I am using this list of strings to compare a Text in a TextBox1 while typing to determine if this TextBox1.Text already exists in the list. I am using the following code (where "s" stands for my List items):
Private Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If TextBox1.TextLength < "1" Then
Button6.Enabled = False
ToolStripStatusLabel1.Image = My.Resources.pic_Add_Warning
ToolStripStatusLabel1.ForeColor = Color.Red

I have a tab control application, each tab loads a particular user control and each of those user controls will then add other user controls that are used amongst other the user controls. For example, I have an "ucQuotes" page and an "ucInventory" page, when the specific tab is selected, the "uc****" user control is loaded on that page, and in the case of "ucQuotes" and "ucInventory" they both use a control called "ucPartNumber"; a user control consisting of a combobox, textbox, and button. I have no issues reusing the shared user controls, in this case. My problem arises with my "ucQuickPrice" control, as it is always present at the bottom of the tab control form (separate from the tabcontrol, but on the same form), and it too uses ucPartnumber.
Here's my issue, as I type into the ucPartnumber combobox, the text I type does not appear in the combobox, it appears in the textbox of the ucPartnumber control that is being used on the tabcontrol page. There are no shared instances of ucPartNumber, nor do I have this issue between typing on one tab page and the text showing on the user control of another tab page.I tried just creating the ucPartNumber controls on the ucQuickPrice control, not adding a new instance of ucPartnumber on the .Load event, and the issue persists.
The combobox(s) in question are bound programmatically with about 40,000 items, ".datasource = dataset.tablename" not to a bindingsource. Autocomplete is set to none, I added code to utilize tool tips and the basic combobox filtering functionality. Is this a bug, or is there something I'm neglecting? I'm about 95% complete with this application, and this just happened today. I made the decision, to just reuse the ucPartNumber control on the ucQuickPrice control (originallly it's size and orientation would not fit, but I added some coding to detect what parent is adding ucPartNumber and to change its appearance accordingly). Before, I made this change, I did not have this problem. And, in trying to go back to how I had things set up before the change, the problem will not go away. if the whole control within a control verbage I used is a bit confusing, let me know and I'll try to better explain what is happening. At this point, I'm going to close and reopen vbexpress, as when I started this ordeal, vb started acting weird and wanted me to save all my work, it usually does this before locking up.

I have a Data Table Column with multiple Rows of data. I need to search all lines of TextBox1.Text for any data that is identical to any row in the specified data column ("MCaddRG"). Also any identical findings need to be made into a new text file or a new form with a text box.[code]...
*Also if it is possible I would really like to have a check box list that contains the data from the "Device" columns so I could check the "Device" and then it search the TextBox.Text for the checked "Device's" "MCaddRG"

I have a completely basic program here that I want to simply take text from a textbox and the selection from a combobox, and then run the following:
CODE:
Obviously WKID and PROCESS are the variables it will be pulling from the data that was put in by the user. That code was just in a simple batch file that I made with 2 variables. I am wanting to pull those 2 variables in when clicking the "kill process" button, it will run a command simliar to the above and end a process on a remote networked computer.

I've a got a homework assignment that chooses one of four values in a list box, stores it in a text file. Secondly, on the display click event it should access the text file, read the line, store it in a variable and then display the totals in a text box. Works sort of fine except that it doesn't display the totals correctly. Code for both buttons is below. The variable are assigned in the mainform (Tried also in the display button and didn't change anything). The save button works fine and stores fine in the text file, it's just the reading that's the problem.
Private Sub saveButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles saveButton.Click

I'm trying to figure out a way to compare two "salted-hash" strings. How can I do this? I know that the salt is a random generated value that's appended to the plain text, then we just compute the hash of that new string.So how can I compare these two values? O_O (The new hash that the user hash written in a textbox and the hash stored in a database)
