Display Control In .NET That Can Handle Color Codes?
Jun 12, 2011
It seems the only options available to do multi-color on a string is either a bunch of label controls cleverly grouped together or to use a RichTextBox and play with the font properties as text is added to the control.
What I am looking for instead is some kind of control that can render some style of control codes out as color. Consider bash codes:
NORMAL='e[0m'
GREEN='e[0;32m'
BLUE='e[0;34m'
echo -e "This text is ${GREEN}green${NORMAL} and this text is ${BLUE}blue${NORMAL}"
In the above, the words 'green' and 'blue' will be colorized with their respective colors. I was wondering if there was a control with some kind of feature like this, or will I have to code something myself?
Note, I only have the Express copy of VB 2010, and I would very much like to avoid third-party controls.

I have made a program that when you type {P in a rtb it erases the {P and makes the text purple. When I try to paste the rtb.text to a new rtb it loses the color codes. Is there a way for the text that is purple to stay purple?

Every single time that I want to copy and paste the code that's been color coded, I have to sign into MSDN, choose Insert Code Block, and then Paste my VB.NET Code, choose VB.NET, Click Preview, and Copy and Paste it to an HTML Page, I Want that thing that color codes my VB.NET Code, in order for me to share my work online... I don't want to have to keep comming on here and doing all that just to get the HTML Version of my VB.NET Color Coded CODE..Do you understand what I'm asking...? Where can I get software or HTML that will color code my VB.NET so that I can Copy and Paste it to SeaMonkey's Composer page.

I have a TextBox that displays a color as its background color and the background color code in its text. I have set the text color as Black.The problem is that if the user sets the color as Black then the color code will be unreadable. How do I set the text color programmatically so that it becomes readable when the user selects any color?

I need to be able to write data to a binary file. No problem - I have a test app I've knocked up that reads and writes to them fine, however the format uses C0 and C1 control codes, and I have no idea how to write them properly. The SOH, ENQ, DLE, NUL type of thing. I'd post some but they are non-printing. I know what they mean and what they do but have no idea how to write them.Basically we are writing our own system that generates test data files for import by another program. My files that I write have the correct number of fields and correct value and formats but because I can't get the tags to write they data is imported incorrectly. I've spent days reading up on it but can't find what I'm looking for.Not dealt with binary data files in VB before so this is all new.

I'm not sure if this is the best forum for this question but it seemed like the most applicable. I am using VBA to create a barcode label application that sends a series of ZPL (Zebra programming language) commands to a USB printer.I need this program to be stand alone in the sense that the Excel 2007 workbook that I am embedding the macro in and the printer driver are the only software that will be required to sucessfully run this program on various computers that have Excel 2007 installed. Additionally I need this program to work directly with the USB port and not a serial/ usb converter. Can someone help me, or direct me to help, to perform this kind of operation? I used to be able to read and write to serial/ parallel ports and haven't worked with USB from a programming perspective.

I've looked throu all of the SendMessage(messages) but there does not seem to be anything like WM_GetPos.Now I can accomplish through AHK with ControlGetPos, but for the life of me I can not figure out what Win API function they are calling to accomplish this.We have an order entry system we use, that I am trying to automate the printing of our reports (we have 4 per order form) to save time

I have a basic VB.net app that displays a picture box with some text. nothing special. looks fine on my computer. If I display it on someone else's computer with a larger font size (125%?) my picturebox and text looks off and stupid.
How do people account for this? Should I simply get the new font size and multiple all positions, lengths and widths of object by 1.25?
I'd obviously like my dialog to scale properly and look as expected in any display no matter what font size is selected.

I have a problem with a control leaking GDI handles.
This is the cut-down version of the control:
Public Class FancyLabel
Inherits Label
Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
[CODE]...
When I run the program, the GDI object count is 38. Then I open a form that has only one FancyLabel on it and the GDI object count gets increased to 42. I then close the form and the GDI count falls down to 39 and stays there no matter how many instances of the form I create and close.JV

I want to have my current row stand out as the current row by virtue of the background color.I also want my current cell stand out from the row color.
in other words i want to controll the background of the current cell as well as the current row, and have these colors different from each other as wel as the background from the non current cells.
I am getting confused with the notion of the current row vs the selected row.I have tried messing with the default row style.selectedbackgroungcolor as well as the same for the default cell style, but cant get it to work the way i want.
i can almost get it if i set the selection mode to full row, but then cannot get the current cell to have a different background color.

I'm inheriting a couple of the common WinForms controls and then manually repainting them so that they will correctly render over a WinForm with the Aero Glass effect enabled. I have this working well with the TextBox. I ran into a snag with the ComboBox though in that it would only repaint some of the control. I fired up MS Spy++ and saw that the ComboBox has an Edit control in it (that's not in it's control collection). I can repaint that Edit box, but I need to get the handle of it and a couple of my attempts have flopped. I found some code that used the FindWindowEx API passing the Comboboxes handle but for me it returns 0.
hwndEdit = FindWindowEx(Combo1.hwnd, 0&, vbNullString, vbNullString)
Basically, I need the handle of the edit control inside the combobox (once I understand how to correct get that then I can get the additional controls in other ones I want like the ListView). Here's the Spy++ screen shots to illustrate (from Spy++ I can see the individual handles).

I use VB.NET 2010 I have created a user control which holds a few textboxes, where the user can find articles. This user control is added to several Forms (where ever the search is needed). I have to handle the key down event of the user control, but it isn't working... The usercontrols's Key_Down Event is never fired. - I have set KeyPreview of the form to true, then the Key_Down of the Form is fired.

My application uses an MDI form, and there are instances where the end user will need multiple child windows open at a time. I need an easy way for the user to switch between windows, which made me think of using tabs kinda like Firefox, or like the tabs in the Visual Studio IDE up at the top where you can switch between open forms and code files.
I'm curious if there is a control in .NET that will already do this? I would rather not re-invent the wheel if I can help it. Google has failed me thus far.

My VB.NET application generates an HTML table with numeric data. I wanted to format the numbers with commas and put brackets around negative numbers. That i did by specifying the format string in the ToString() method. What i want to do is change the color of the negative numbers to red. My sample code:
...
rowHTML.Append("<td align=""left"">" + num.ToString("#,##0.##;(#,##0.##)") + "</td>")

I show a waiting form (saying "Please wait...") on a different thread when there is long-running code in some forms (for example, during data loading). I show the form like this:
m_PopProcessingThread = New Thread(New ThreadStart(
Sub()
m_PopProcessingForm = New WaitingForm(m_Message)
Application.Run(m_PopProcessingForm)
End Sub))
[Code]...
The stack trace points to the part of code where I hide the form. How could the handle not have been created, when just before the Invoke call, I loop until said handle is created?

I have a problem whereby some rubbish code is not releasing its memory (eventually reaches the 10k handle limit and crashes).I'm looking to insert some logging in the application to dump a list of handles present at the point of failure.
