DataGridView With Two Text Colors On The Same Line
Mar 30, 2009
I am trying to find a way in VB using Visual Studio 2005 to have two different colored text on the same line of a DataGridView using the cell painting event
I am trying to accomplish the following.
ABC QRS
DCR BBL
Where all letter B's are Blue and all Letter R's are Red.
I have searched and found someone requesting the same. They had an example of how to do this on two different lines within the same cell but not on one line.
I don't understand the code well enough to make the change and several people that responded gave the code equivelant in C# instead of VB
The Code that they had was as follows:
If e.ColumnIndex = 0 AndAlso e.RowIndex > -1 Then
If e.Value IsNot Nothing Then
Dim lines As String() = e.Value.ToString().Split(ControlChars.Lf)
I have a simple problem to solve: dispay row in my datagridview in alternating colors, say Gray, Blue. I'm connecting to an Access database, and pulling records out of a single table as shown in the code below:
I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt" edit_input = New StreamReader(user_data_file) Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.
I have a big datagridview that has a list of items, that have several states, every state has a date. My dgv will look like this:
----- Date1 | Date2 | Date3 ... It1 | It2 | It3 |
The same item can have multiple states in the same date, for example: The item1 enters the factory in the date1, and leaves the factory in the same date1, what i need it's that the intersection cell, have one line with the background in green with an F (means that the item enters in the factory), and in the same cell, but in another line (multiline) in the same cell i need another F but this time with the background red (means that item leaves the factory).
The usuals columns doesn't allow me to do this, i created a simple code to use a image column and then draw a image that does what i want, but i don't like the final results and it's a little slow, and when i select the full row, i don't have the usual selected cell visual effect in this columns... I was thinking to create a datagridview column with a different type (inherited) but i don't know what column to use as base column for my column, image column and then paint the content of another control in the cell or another type?
have more than one text color in the Rich Text Box, because when I highlight one word and use the color changer, it changes ALL of the words in the text box, and I want to know how to be able to have a specific word, or words, be a different color.
This has worked fine, until I set the "Enable XP visual styles" on the project properties page. With this set, the colors dissapear from the header (although they still show up correctly in the grid). If I turn the flag off, the header colors are back to normal.
Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.
I am developing a program where i will download and save an xml file from a url as abc.xml. I open the abc.xml in a datagridview with a dataset without problem.I am confused how can i read raw per raw the datagridview and assign the data in a database table? i am using vb 2008 + msde2005 express.I show the whole content of the xml file in the datagridview with the following [code]I dont know how to create a loop where i can read the datagridview line by line save data in variables (ex.strings) and save it in a databese table?
I have another application that i'm currently building...
It basically is a "check list" for installed program's, and files. I image machines on a daily basis, and me making this application will save me hours, and hours of time.
It's purpose is as follows:It basically is a "check list" for installed program's, and files. I image machines on a daily basis, and me making this application will save me hours, and hours of time.The basics:My program basically has 2 forms. 1st form, will be tabbed with "clients" or, different model of PC's. Each tab will have it's own checklist. I know how to pull external files already, though, that's not my issue.Basically, when I click "check list" button, it searches for an "adobe", and "Labtech" Directory. If it exists, it will throw the result into form2.richtextbox as Adobe is installed, or Adobe is not installed. Also, Checks if the second program directory is there, and then imports the info into form2.richtextbox on a seperate line. My question is, how do I change the color of the text per line?I.e. make Adobe is installed turn GREEN, and Adobe is not installed turn RED ect.
Form2.Show() Form2.Show() If Directory.Exists("C:\Program Files\ATI") Then
I am using vb.net in my project. I have a datagridview bounded to a datatable m_table which has a column called Price_Change with decimal values. I want to display text in datagridview in green if price change>0 and red otherwise. I cannot simply use the following formatting because the bounded data table m_table is constructed in my code, not directly through data base.
Dim rowText As DataRow = m_table.NewRow rowText("Price Change")=10.00 'assign values to price change column
' there is no color formating for data table I wonder if cellformatting event can be used for this purpose. Would it slow down the load of datagridview? [URL]
how to change fonts/colors/sizes and stuff from line to line inside of a richtextbox. Because whenever I try, a beginner, I always make the entire richtextbox change colors/fonts/sizes etc, rather than just a single line. So mainly... i just need to know how to change primarily colors for my chatbot guy and the user. :"We are what we repeatedly do. Excellence, therefore, is not an act but a habit." Aristotle
Is it possible to Insert text with different color in the same list box ? For example , the contents of the list box could be :Line 1Line 2Line 3Line 4
This is a WinForms Application in VB. In my application I am trying to make it easier for the user to pick out items in a list quickly based on the items text color.. So I am trying to assign the color to each item using a select case statement as below... The problem is that I am getting an error saying "Public member 'Attributes' on type 'String' not found." VB flags the lines with the Attribute.Add param with this error.. Here is the code that I currently have...
For Each u In _units _counter += 1 u_lookupNumber_box.Items.Add((Convert.ToString(u.UnitId)) + " - " + (Convert.ToString(u.perMonthCost)))
[Code].....
I did notice that when I did the .attributes part when I hit "." and typed "att" it did not appear in the intelisense box in vb.. Which makes me think I need to assign the name "attributes" somehow to the dropdownbox first.. It should be noted that u_lookupNumber_box is the name of the drop down box on my form..
a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

I have a couple of VB6 programs which work 100%, however not under W7, so I need to upgrade them to Visual studio 2008 pro which I own a copy of.The VB6 software used to open a file, read in a line of data and process it then save it in a new file, before going on to the next line input.I need to convert this process to VS2008 pro and can't get my head around it..... getting old you see.I also have a few other needs to do with file handling, but I may be able to sort them myself if I get a start with the above problem....
I have to create a new program that reads to Text files. These text files are in the form of a report (with column headings). The purpose is to compare each record line by line to see if their have been any changes made. The record is based on an Account#. Over time these files will be considerably large. What is the best way to do compare records from each file. I'm thinking loading each file into an array and processing them that way.
I must use streamreader to read text file line by line into array.
Here's what I've got.
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click Dim numbers() As Double = New StreamReader(txtfile.Text) Dim numbersarray() As Double
I just joined this forum as I've been looking for a nice and serious VB forum for a long time
I'm having troubles making a program to search a text file line by line for a specific string.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim objReader As New System.IO.StreamReader("C: est.txt")
[Code]...
as you can see in the code its supposed to read a text file and if the line contains the same string as in the textbox then its gonna make a messagebox.
now the problem, if the line does not contain the specific string but the next or any line other line does, then it should automatically read the next line on "Else" and that's where I'm lost
for a "Readnextline" command or something like that?
I have a list of random numbers in my text file.I read it like this.
Dim FILE_NAME As String = "C: est.txt" Dim TextLine As String If System.IO.File.Exists(FILE_NAME) = True Then
[code]....
How can I separate that in to 2 listbox?In my ListBox1 I want add lines with starting number like this ( 0905, 0906, 0915, 0916, 0917, 0926, 0927 ) And in my ListBox2 is with numbers start with this ( 0909, 0910, 0912, 0918, 0919, 0920, 0921, 0928, 0929 )How can I compare lines by multiple choices like that?
Dim sFileName As String Dim srFileReader As System.IO.StreamReader Dim sInputLine As String sFileName = "D:UsersArbenDesktopSerieA.txt" srFileReader = System.IO.File.OpenText(sFileName)
[Code]...
under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file
the following code was to be entered to read each line of the file "line by line" It did not work for me as instructed and I am trying to understand why?
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim FILE_NAME As String = "C:UsersOwnerDocuments est.txt" Dim objReader As New System.IO.StreamReader(FILE_NAME) Dim TextLine As String
