View 5 RepliesI have used thirrd party tool from BigSpeed for file transfer. When ever I am trying to assign a value from (txtUserName) to the property like
FileTrans.GetUserName=txtUserName.text.trim
It gives error as Readonly property..... That means I can not assign a value to it.
I am writing an application that will use a OpenFileDialog control that will read a text file into memory and later process it.
I do have the following filter: Text files (*.txt)|*.txt|CSV files (*.csv)|*.csv|Spaced Text files (*.prn)|*.prn|All files (*.*)|*.*"
When I navigate to my test folder that contains a single .txt file, I see that file. When I change the filter to *.cvs that files goes disappears because it has a .txt extension. That is good. But when I select All files *.* it does not re appear? Why and how do I make it appear.

View 2 RepliesFor the page I'm developing I need a DropDownList with CheckBoxes on it, so that the users can choose more than one option without having to use the Ctrl key (and it's more intuitive). Because my options are being retrieved from the Database, the list of option can be really big, so using a CheckBoxList would use a lot of space. with this? I'm almost desperate! I have been search for a couples day, but having problems in everything I tried. What I'm trying to do now is override the DropDownList control (as suggested in this forum: [URL]), but I'm having problems right in the first line:
[Code]....
I found somethings and modified a bit the code so its can fit with what i needed.
I got it to work. Its read the text file but not i would like it to read.
In the ListBox, the text show up in 1 line as it should show in multi-line... (Yes, in the .txt file the text is in separated line.)[code]...
I'm using ASP.Net 2.0. I have a custom control that is inherits from a 3rd-party vendor's control. I'm trying to override the Render method.

View 1 RepliesScenario: Every page on the website will have a menu bar at the top consisting of a number of buttons. Some pages have the same amount of button that do the same thing (example redirect to a page) but some of the buttons depend on information currently on the page.Problem: I would like to be able to override the buttons on the control so that I could handle it per page. I was also thinking maybe it would be easier to use events and handle it that way instead. Are either of these approaches possible and if not is there an alternative?The code I currently have is below
In the aspx page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I have a usercontrol with a picturebox and a few buttons related to it, such as LoadFromFile, Paste and Zoom (that last one pops up a new form). Is there a way to override the basic Enabled property of the usercontrol so that I can keep the Zoom button active all the time, while turning off the other buttons?
I realize there are 2 "obvious" replies. don't do Enabled=False, create a custom method. do everything in the one form, not a usercontrol, so you can pick and choose disabling. Both are less than ideal, given that I'm putting this control into a couple of existing forms, so I'd like to work around how those forms already behave. So is there a way to override the behavior of my usercontrol when it gets disabled? What would be my best strategy?
I want to modify this code or replace it. I want to override the the textbox's textchanged event in a user control.

MyBase.OnTextChanged(e)

View 1 RepliesI am working on an assignment, so need to pass the file to the instructor. I thought I remembered a way to input a placeholder character(s) that tells the computer that the path is flexible until the point where I declare the actual path.
For example: if the directory is C:documentsMyProjectinDebug on my machine, and is F:usersownerclass assignmentscis101StudentAMyProjectinDebug on the instructor's machine, can I put a "wildcard" type of character that points to the ...MyProjectinDebug file that will work on both machines in the Initial Directory property?

View 1 RepliesI'm working on a project where I need to trigger an event when a switch is closed. It is my understanding that it is possible to use the control lines on a serial port and read whether the switch is closed or not. I've found a schematic of how to connect the switches to the pins, but I have not been able to find any example code on how you can read the state of the switches.

I'm probably missing something really simple or trying too much at once but it's 16:30 on a Friday afternoon and my head is wrecked Basically, I'm trying to build an application that takes out put from a database query as XML and uses XSL to transform it into HTML which is then displayed in a web browser controll on another form.
I thought I break it up into pieces so I decided to just create an XML file and an XSL stylesheet and read this into the web browser control but all I'm getting is <HTML></HTML>

I'm trying to make an application that can read a 12 byte hex string from the serial port and display it into a text box, the source is a RFID module that is connected to my USB port using a RS232-USB converter.My first problem was accessing the text box in the datarecieved event due to invalid cross-threaded operation. Upon googling that, I copy/pasted the code I needed to get it work, these are all the cross threading functions.The OpenPort function and Datarecieved event are my own code, the rest I got off google. The application then worked, but I would get an incomplete code, the first swipe I would get all 12 digits, and at every other swipe, the first byte would vanish. Upon some more reading, I decided to make an array, the size of the incoming data (shown in the code below), but now I get the cross-threading error again.I know there's something wrong with the way I'm using the array. This is way beyond my VB knowledge, and I'm in o I'm an electronics engineer and self taught myself a little programming to create some apps for my hardware.Updated code:
