So, I'm currently working on sending and receiving data via a serial port. In order to use readline, I need to send vbCrLf, which is fine. I'm trying to get it to display just the characters sent and not the additional characters like Cr and Lf. Here's the most basic part of my
SerialPort1.Write(HexSendBox.Text & vbCrLf)
ReceiveBox.Items.Add("Received: " & SerialPort1.ReadLine())
The data I will receive in the ReceiveBox if I seng 'GG' is:
I am currently working on a project in where when a Coordinators ID is selected from a combo box, I need to strip an XML file and place the subject code and name in a list box. ("code" - "Name" - "Department number"). The xml file is written as follows. The main problem I am having is the fact the coordinatorsID is after the subect code, I have never dealt with this before.
I'm trying to reduce as much as I can my VB.Net assembly side, and I just figured out that all variable names were kept unchanged in the actual assembly. Since I tend to use pretty long var names, it adds up and, by running dotfuscator on my assembly, I could shrink it by as much as 10%.
I need to find next highest no in a field that is a stick ref it has chars at front and 0 padded How so I strip off front chars and 0's to get actual highest no number in the table field?Am using LINQ against entity framework?
I'm essentially re-learning VB for the first time in 15 years to try and accomplish this task - I have a project to do for work which involves taking .doc files which contain hundreds and hundreds of names, addresses, e-mail addresses, and amounts they donated to the non-profit I work at, and inserting them into Outlook's contacts. I'm trying to piece together the bit I've figured out about Outlook/VB integration to do so, but unfortunately, most of the information I can find is the other way around - getting info FROM Outlook and inserting it elsewhere.
The doc file is essentially formatted like this: FirstName LastName 423815 Central Park West FirstNameLastName@Somthing.com $3000.00 And repeat.
So for the email addresses, I obviously need to look for the @ and copy from the previous space or line break to the next - that's the theoretically easy part, along with the money donated, since I can similarly look for the $. The part that I forsee stumping me is, how to discern first and last name, and treat them accordingly, entering them into the right fields in Outlook? Same with the address.
I'm writing a small program that loads a folders contained file names into a list box, you then double click one of the file names listed and it appears within the programs text area where the user may freely edit it. I then have given the users options to export the data contained within the text box to a word template. What I'd like to do is add a button which the user can click in order to strip away all the html within the text areas content. I found a solution but for some reason I can't make it work. There are no errors displaying nor does the program crash out, it simply isn't doing what it should be doing.
The function I'm using is below: Function stripHTML(ByVal strHTML) 'Strips the HTML tags from strHTML using split and join 'Ensure that strHTML contains something If len(strHTML) = 0 Then stripHTML = strHTML [Code] .....
I've used the below snippet in an attempt to put the function to work in the text box. Private Sub btnHTMLstrip_click() ' calls function stripHTML, applies to text box richTxtBox.Text = stripHTML(richTxtBox.Text) End Sub So, its not working as it should?
I have a html string like this:[code]I wish to strip all html tags so that the resulting string becomes:From another post here at SO I've come up with this function (which uses the Html Agility Pack):[code]
Essentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.
Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!
I have two textboxes. I type in one of them and the text gets copied in real time into another textbox. There is one catch. I need to replace specific character with something else.
If I enter a quote " in textbox1, it has to be replaced with " in textbox2.
I started with something like the below code, but obviously this does not work (tried different stuff - this is for demonstration only). In the example below 'a' represents " , and 'b' represents "
Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp TextBox2.Text = TextBox1.Text
With the shape of really large characters such as numbers and alphabetic characters + others, is there a way to get that shape as a REGION please?Imagine a really fat snake forming the letter S or two rectangles placed together to form a large letter L or a T like the shapes in TETRIS.
1) Does anyone know of anything in VB.Net that can translate such shapes into a System. Drawing.Region or know of a project elsewhere that achieves this please?
2) While I'm on the subject, how would you SCALE UP / DOWN a System.Drawing.Region please? How would you work out the Transform Matrix required please?
I'm making an application that will change position of two characters in Word.
[Code]...
Program works good, it is mixing characters good, but it doesn't write text to the file. It will write text in console, but not in file. Note: Program is working only with words that are divisible by 2, but it's not a problem. Also, it does not return any error message.
I'm making a custom control suited for handling passwords. I have created a control that inherits from a text box and I have implemented a lot of things so far. But what i want to do now is create a system so that when a user types It will display his last character typed for a X amount of time. Is there a way to turn only selected characters into password characters and still be able to get the password text from the Text property ?
I have a parent/child relation I am trying to create fow 2 datasets.The parent ds consusts of a range of PO Header information
After I fill this dataset I loop through it getting the PO number. I then take that value and execute another sql statement on the DETAIL file and fill a dataset(dtlDS) for EACH row in the parent. How do I add to this dtlDS for each row? I am getting no CHILD data in the merge. Should I be filling to a datatable and do an add.row and THEN dump into the dtlDS?
adding certain functionality to an existing ASP.NET application running on IIS 6.0 programmed in VB.NET.To aid in future development the client wants the additional functionality to be as future proof as possible. Ideally i have said that I would like to push for a solution using ASP.NET MVC3, running off IIs 7.5 and .NET 4, written in C#. This solution would act as a seemless addition to the current web-portal appearing probably just as an extra tabbed page.
But they will be completely seperate web-apps. Which is crucial.The main problems i can forsee are firstly sharing session particulars between the asp.net web app and the new application. Particularly with regard to maintaining session state (and not having IIS timing out on one of the apps). Also, conjoining the two "apps" appears problematic in my head, although this may be far simpler than i fear.
1) Embed the new fuctionality into the existing codebase (not a great option). This would mean losing any potential future upgrade-ability and also means not following better OO conventions by utilising the MVC framework.
2) Using an iFrame to link to the razor pages of a seperate MVC3 app (the one im favouring currently). Allows uses of all new technologies, however downside is sharing session data. Either through iFrame "attributes" through persisting a session state to a db? (slow?) or even some kind of web service interaction between the applications to push/pull user/session data?
Im practicing a database and I have a 3-column table. Im using binary formatting to save/open the file. I cant see what is wrong with my code“
I can display records ok when I press the save button
I can also save the records ok when the save/close button is pressed.
When I reopen the programme and press the reload button to reload the dataset, additional records will not be displayed nor saved though original records will be showing.[code]...
Im trying to get a sales percentage program to work and im having trouble on the last part. My homework is to get the original price from the customer and then take the sales percentage off and show how much it is. Then after the first percentage is off take an additional percentage off part and then show the grand total. I got all the way up to the additional percentage off part to work right. I dont understand why I cant add an additional percentage of and the program wont recognize it and work right.
Public Class Form1 Dim Num1 As Integer Dim Num2 As Integer Dim Num3 As Integer
We have a big Form class that we like to split into peaces using partial class approach That could be done by manually modifying a project file, and adding MainFormPN.vb entry
The issue with this approach is when double click on this item in VS2008 IDE it shows new empty form, not MainForm UI. It looks like VS2008 does not support multiple partial classes for a Forms.
I am using a webbrowser control and loading a website that uses basic authentication. I pass the username and password in the additional header of the navigate routine. The problem is that the header is not retained while navigating the site.
I.E.I log into the site and pass the user name and password in the http header. When I click a link to access another page the header is removed and the site asks for credentials. If I was to just type the site into IE and log in the first time the headers are carried forward on all pages. how I can have the page retain the headers so the user never has to authenticate?
Dim sHeaders As String Dim HelpBrowser As New WebBrowser sHeaders = "Authorization: Basic: " & System.Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes("UserName:Password")) & Chr(13) & Chr(10) Me.HelpBrowser.Navigate("http://www.mysite.com", True, Nothing, sHeaders)
I need to add an additional dimesion to outputArrayOfBits() in the code below which I hope conveys my intention. I need to convert a one dimensional array of 1 to n boolean (bit) values into arrays that group them by 8's so the output can be consumed by someone needing these values to be in hex format (0000 1111) = 0F How do I change the declaration of 'outputArrayOfBits and the nested control loop to achieve that?
Dim inputArrayOfBits As New BitArray(32, True) ' I can't change this. 'Create array of bytes containing what will be sent out has hex numbers 0 - F 'outputArrayOfBits(0) = (1,1,1,1,1,1,1,1) 'Hex value FF
I have a gridview which shows selected data from a database all the columns will popup dynamically. but now i want to add an additional column with a list box is it possible or just a column will be fine
I'm am very new to Vb.net, I have coded in VBA.I have created a form that will open Microsoft Excel, add header text to the columns, and insert the text from a few of the controls located on my form ("not finished adding controls") when I click the Submit button.
My problem is that when I enter different data into those controls and click the submit button again, I get a new Excel Workbook with the new data.I need the new data the be submitted to the .Activecell.Offset(1,0) of the already open workbook.Ultimate Goal of Submit button is to open new Excel workbook, Enter multiple rows of data via Visual Basic Form.
Im trying to add data into a new column I have created in my gridview.[code]...
Now I need to go in and add data for the rows below the column. I have seen ppl saying I need to set it equal to a datafield but how do I create a datafield from scratch then?
I want to show tblProductComponents and have only the PercentValue the only value that can be updated. But, I also want to show the component information as well.I can do this in a view but then I lose the update ability using the tableadapter.
