Forms :: RichTextBox - Search Feature And Match Case
Mar 28, 2011
Here's the situation: I've got a form that has
- RichTextBox
- OpenButton (to load RTF file)
- SaveButton (to save RTF file after editing)
- Textbox (for search phrase)
- SearchButton
- ExitButton
- 2 RadioButtons (WholeWord and MatchCase search)
All of them are working just the way I want them to except search features; I don't know how to write them properly. At the moment, they search and highlight only the first word they encounter. E.g. say I search for word "the" in the document, only the first "the" it encounters is highlighted. The rest is just untouched.
I understand this is because I've only got few lines of simple code as follows
If rtfText.Find(txtSearch.Text, RichTextBoxFinds.WholeWord) = -1 Then
MessageBox.Show("No results returned. Please try again.", "No matching results.", MessageBoxButtons.OK, MessageBoxIcon.Information)
End If
I did try a few other snippets I found on the Internet including While loop but they didn't work as I wanted them to, and I couldn't understand them either. What I want is, which ever search option is used, when the matching result is found; it will highlight that word and when I click it again it will move onto another word. If I keep clicking, it will highlight the same words (but located in different areas) throughout the whole document and at the end, it will send back to the first matching word. Just like Adobe Reader search.
I have very complicated, unnecessary code because I wrote it myself and this is a new concept to me. The code is intended to find a string in the main window's RichTextBox (the string is obviously supplied by the user). The code works fine, but due to its convoluted nature, I don't know how to implement a "Match case" function.
The form has these controls (at least the ones you use when searching for text):
Textbox: "txtFind" - User enters a search term here
Checkbox: "chkMatchCase" - Allows a user to choose whether or not to match the case of the search term
Button: "btnFind" - The Find Next button
And this is my code
Dim index As Integer = 0 Private Sub OK_Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFind.Click Dim strSearchTerm As String
[Code].....
Anyway, if there's a better way to implement this, please let me know. And I did extensive searching, but found no good solution. I ended up combining a bunch of little parts of other tutorials into this. If there's no better solution, I'd just like to know how to implement a "Match case" function.
I am trying to make a search feature in my program. My program has a .csv file that the program will need to search for a equal value that was entered in thr text box. I am just not to sure how to go about this. Just need some insight on how to grt started. Insight please.
I want to add a spell checking feature to my richtextbox but i do not want to use MS Word or any other application to spell check for me. I have got a list of words for the spell checker in a .txt file with each word on a spereate line.
I am trying to do a record search feature in my datagrid, but I can't find any reference for this. What I want to do is I can search any of the row that contain the text that type in TextBox1 by clink on Button1. I am using VB2008 and the datagrid is connect to access.
I have a richtextbox with a large file inside....I want to be able to search for "Fornication" within the text (KJV Bible) and have every instance of that word to pop up into another richtextbox along with the scripture it is in.
I am in VB.net and wondering if there is a way to call a search from a console application.For example when the user clicks cancel on the Input Box it brings up the file browser for their computer allowing them to choose a place to save the file.[code]
I created 2 forms in Access 2003 (Form1 & Form2) for the purpose of creating a 'smartform' of sorts for my company. In essence they can click on a search feature in the top cell and input an employee ID # which automatically fills in about 10 to 15 fields.
- There is only 1 table attached to the forms.
- The group I created this for is uncomfortable using Access.
What I would like to do with VB.net:
- I thought I would create an internal webpage using VB.net so they wouldn't need to log into Access [the DB would be stored on a separate server.]
- I would need a clean & simple interface that has 2 buttons, one for each form.
-When the form is called up I would need a search feature "EMPLID _________" which would connect to the Access DB table and retrieve the correct information.
-Id also need to have the form printable & have the ability to search again or return to the front page.
I'm creating a search application that needs to have a fuzzy search. Basically if there are 0 results, I need to provide a suggestion, much like google. For example, if I type "Californea", I need my program to suggest "California" after doing a query on my DB for similarity.
i have a listbox, that i want to make sure the value im about to add to it, is not already in the list, here is what i have but it dosent put anything in the list box.
For Counter As Integer = ListBox1.Items.Count - 1I To 0I Step -1I If InStr(CStr(ListBox1.Items(Counter)), hyperlinked(0)) < 1 Then ListBox1.Items.Add(hyperlinked(0))
I am having problums with Ignore Case in searching. I got a checked listview and a listbox, it searches and fines just the exact word. For i As Integer = 0 To (Me.Special_Search_Histroy_CheckedListview.CheckedItems.Count - 1) 'Dim itemString As String = Me.Load_Search_name_Listbox.Items(item).ToString Dim strr As String = (Me.Special_Search_TextBox.Text) Dim path As String = (Me.Special_Search_Histroy_CheckedListview.CheckedItems.Item(i).SubItems(0).Text) Dim readText() As String = File.ReadAllLines(path.ToString) [Code] .....
Dows anyone know how I can build a timeout feature into a windows forms app.
The app is event driven, but I am thinking of somehow using a timer which counts down for say 10minutes, and one the timer ticks then we time out the user.
The problem I have is how can I reset the timer each time the mouse is moved or clicked.
I'm trying to search files for matches, and depending on what catagory the match is under, do a certain function... Say I have a .txt file that looks like this
[Code]...
Then I have a form with Button1 and Textbox1. Say I type "Cat" into Textbox1 and press Button1. It would then bring up a MsgBox that says "Match found under Animal catagory". But if I put "Three" in Textbox1, the messagebox would say "Found under Numbers catagory".
I've been using text.indexof() to see if a string is located inside another string, however is it it possible to do a case sensitive/insensitive search option? I've been looking around Google and not having much luck with it.
A huge bonus would be if it could count the number of occurrences inside the string!
I've recently learnt that Regex class maybe used to develop case insensitive searches. I have a registry search program that will return only the exact matches from the registry. I need to make it case insensitive. how to do that using regular expressions in vb.net 2005. Im posting my code below:
Sub SearchSubKeys(ByVal root As RegistryKey, ByVal searchKey As String) Dim matchtype As String = Nothing Dim str(5) As String
I am trying to add two features to my webbrowser: View Source and Find. Does anyone know how to get the webpages source code and a method to perform a search in the webpage? I was thinking one might lead to the other.
I have a Microsoft LifeCam Cinema Webcam. I have written a simple application thats STARTS the video capture, STOPS the video capture, captures a STILL image and CLEARS the still image on one form using TWO picture boxes....one to hold the STILL image and the other to show the VIDEO from the Webcam.

I have written a simple application thats STARTS the video capture, STOPS the video capture, captures a STILL image and CLEARS the still image on one form using TWO picture boxes....one to hold the STILL image and the other to show the VIDEO from the Webcam.I am using the VFW(Video for Windows) API to interface to the Webcam and everything in the application is working as intended with NO PROBLEMS. I use No DirectX, No ActiveX/COM, No Intermediary file, just live video stream.I do however wish to control the ZOOM feature of the camera using the VFW API.(increase and decrease)
I have a program that is reading an Excel (xlsx) file and I am trying to take the data found in one of the cells and split it based upon the '@' symbol inside that cell. Here's an example: value in cell is "XXX @ YYY" I declare 3 strings (strOriginal, strA, strH) strOriginal is the value from the cell ("XXX @ YYY") then my code is supposed to split up the values in the Original string based upon that '@' symbol.So when my code is done, strA should = 'XXX' and strH should = 'YYY'.
Here is my code
strOriginal = dtbExcelData.Rows(0).Item(0).ToString y = strOriginal.IndexOf("@") strA = strOriginal.Substring(0, y - 1)
[code]....
For some unknown reason, the y integer (in this case, it is '4') changes to a random number (it has changed to 44, 61, 124) and causes the error "Error with Excel file: Index and length must refer to a location within the string. Parameter name: length" to occur.I understand why the error occurs (my y integer is not staying at 4)...I just don't understand why that y integer is changing numbers when it should remain as the indexof the '@' symbol. I'm looking for any suggestions on how to pull out the data after the space after the '@' symbol (the 'YYY' portion of 'XXX @ YYY'). Also sometimes the 'YYY' is only 'YY' as well.
I have a form that opens another. I want the second form's checkbox to match the first form's after the second has loaded. I tried using MyForm2_Load, MyForm2_Activated and MyForm2_Shown but the checkbox checked state of the second form always changes the checkbox in first form. The code below works if I check the checkbox in either form, the other changes to match it. The problem occurs only when MyForm2 is first loaded. How can I get it to work the way I want it?
I'm trying to implement a search on a richtextbox. i want the scroll to move to the found area only if that area is out of the visible part of the text.
I have a RichTextBox where I expect 100 characters per line. Each line can start with the letter A, B, or C. I may have thousands of lines and most of them will start with the letter C.When the cursor is moved from one line to another and is placed on a "C" line, I need to be able to quickly locate the nearest "B" line above it. It may be hundreds of lines away. A loop to search for the "B" line using GetFirstCharIndexFromLine(x) is too slow.
The user may want to paste many lines into the textbox. If necessary, a mild wait after pasting is acceptable.Do you have any suggestions for a technique to accomplish what I need to do? Even just a high level suggestion like "use a linked list"
I am creating a machinists G-Code editor based on a couple of Rich Text Boxes. I am using one for the line numbering and synchronizing its scroll to the main RTB vScroll event. I've created a menu that populates a text line with a G-Code textual template for each command. The user presses the tab key to step through each input zone.
I have a text box called "txtDescription" and listbox called "lstDetails" and a RichTextBox called "rttFullDes.
When the User inputs the search query into the description box(txtDescription) e.g "books" then it returns all the records that contains the word "books" and displays their Id in the listbox(lstDetails). When you click on the IDs it returns the full description in the Description box(rttFullDes)
This all works fine. But i want all the words to be hightlighted. i have got this code which i found.
Dim wordToFind As String = txtDescription.Text Dim index As Integer = rttFullDes.Text.IndexOf(wordToFind) While index <> -1
I am wanting to make a program in VB.NET that has many files.doc in a specific folderThis program has on top a textbox(txtSearch) with a button(btnSearch)under that this has two listbox(lstOption, lstResult), that are floating a left,one richtextbox(rtbDoc) that is floating a right.I want that when the user writes in txtSearch and click on button then the application will read all files, and find for this string.
