I have created a login form which only allows access the valid users. However when I am trying to validate the username and password enetered when the user clicks the Login button (btnLogin). However I am unable to pass through the username and password in the Select statement, entered by the user beccause it gives me an error that 'txtloginname' and 'txtpassword' is not declared in the LoginProcess Private Sub. How do I declare the texboxes i coded into the LoginProcess Private sub for it to work?
how can I improve coding structure, when there are a number of subs, functions using the same number of lines each time to make,open and close a connection to an Access database?
Can the lines of code to make and add a connection to the Access database be enclosed in one function and then called through function x () each time it needs to be used?
The simple website I am trying to build is a list of banks with their corresponding website. I also wanted the ability to add banks/website with the use of some text boxes and a button click event.[code]...
I want to convert the code at Webcam using DirectShow.NET to C#. It works perfectly in vb.net. I tried converting using an online converter, however I got about 30 errors
am a build engineer of some VB6 and MSVS VB applications. Inotice the directory path (the location of source code, e.g. c:uild_viewsv70r3 ....)information is stored in the generated dll, exe.This gives us a lot trouble, because I can't use another path to build the dlls, otherwise the binary compare tool will say the dlls are different, due to embeded path info is different.We have parallel development, and the code has to be built in different machines, different paths. Is there a way to resolve this
Is there any real point to learn VB besides as an introductory to grasping the concepts of programming? You never (at least myself) hear of any apps like, Winamp, Windows, Firefox, etc. that used VB.
I need to create code to send an e-mail within a coded ui test and cannot get anything to work. I seem to be having trouble getting the correct Import. We use Outlook.
I'm coming from the Winforms world where I trapped everything and handled errors with messages to the user with MessageBox.Show(ex.message) or just logged it.Now I'm in the web (MVC 3) world and I can't seem to find a definitive coded example of how to employ proper error handling. Let me show you what I'm using:
User clicks on a link which runs a controller action:
[Code]...
Then it falls to the catch block, and then routes to the HttpError action.. Twice! and then my Error.aspx view never opens, instead I get either no JSON result or a 500 internal server error... makes not a lick of sense to me. Basically, I don't know what I'm doing.
OK, to make a long story short, programmatically generated data is taken back to the original page and the goal is to have this information cause checkboxes (hard coded into the aspx page) become checked.
Using feedback, the exclamation below confirms that I want the found control ctl to be checked:Dim ctl As Control For Each ctl In form1.Controls
[code]....
I'm not sure what to put for XXX and my gut feeling is this is really easy. ading my question. I went through pages of search results on "VB Programmatically check checkbox" and found pages that should have had an answer that worked
I need to change something that is hard coded into my application - Souds simple i know - however.....In essence what i need is a single word that will be interchangable and will be available straight away and the next time the application starts up.So need to change the word that is already hard coded into the loading of the form.Like an internal password system?
ps. i was thinking of something on the lines of a sub that finds and replaces line 'x' in the load sub. unless that is uber complex - so open to any and all suggestions but please keep in mind i'm not the greatest at code - only been teaching myself for 9 months (and learning from people here for 1 month)
I have a software coded using visual basic 2005. I don't have the 2005 version now and i need to edit that software. Is there any way to retrieve the code using vb2008 or vb2010? If not from where can i download the 2005 version? I need to do it at the earliest.
I'm designing a .NET-Type at runtime by using the Reflection.Emit-Namespace. Currently, I'm about to generate a method which invokes an already existing method in the generating class:
Below is an snippet from my project template. I have some classes I want to link to in the project.One of my developers created the template and I copied it to my PC.It seems to work on his, but when I create a new project, instead of keeping the hard coded path the "my documents" gets replaced.I know this is a little cryptic, but I was hoping to flesh the question out with your questions.[code]
I realize the code listed below, whose serial port using string formatting which I inherited is complicated. It formats a Date obtained from a DatePicker control into a "yyyy-MM-dd HH:mm:ss" string format to send to a hardware device to be stored via Serial Port retrieves the date from the device and displays to user What I'm trying to do is port the code for use in a Socket rather than Serial Port which wants a Byte Arrray of the same Date Time string variable. I can't figure out how to encode and convert to Bytes the string value used in the Serial Port version. The evolution of the process is listed from top to bottom.
I am learning VB 2008 Express Edition to solve the following issue: how do I put the color of each pixel in a table, allocate a code (from 1 to 256 in the case of a 256 colors picture) to each different colors and print these codes at the right place on a grid? A few years ago, I had a basic knowledge of VB6 but VB6 being not compatible with Windows 7, I had to install a new version, VB 2008 Express edition, version that I don't know at all!
On my form, i've got some textboxes and some richtextboxes. I'm using the following code, to search through the text properties of each of the two types of control. see below:-
For Each ctl As Control In Me.Controls If ctl.Text = "7777" Then ctl.Text = "found the sevens" End If Next
What i'd like to do is isolate the textboxes only, is there a way to do that? I tried this but i got an error:-
For Each box As TextBox In Me.Controls If box.Text = "7777" Then box.Text = "Found" End If Next
