I've been looking at API and cURL and I'm thinking of creating a program for delicious which adds a bookmark for me a certain times during the day. They have an API page here which I think you use a cURL command to use but I don't know what any of this means
I reckon I could figure out everything except how to actually get the program to connect to delicious and add the bookmark, there doesn't seem to be anyone else using vb.net and cURL together so maybe there is a reason.

View 4 RepliesI am using vb.net 2010. I have a datagridview whose data source is a data table. I dynamically add rows to the data table.
[Code]...
After adding the new row, m_table is correct. However, DVGCusClient not only adds this row, but also adds two additional blank rows at the bottom. I have no idea where these two blank rows come from. Why I use above code is as follows: Use a data grid view to display data. When a user clicks a row, another form is opened which allows user to search/input some data.When the user closes the form, all data is saved to a data table and shown on the data grid view.
I'm using Visual Basic 2005 Express Edition and I was just wondering if someone could help me out with a few things? I'm making a Notepad-type program just to clarify things.1. I have a button which adds text to my RichTextBox1 (excuse the name), but when you click it it adds text to the end of the script. I want to make it so the text is added where your "cursor" (the blinking thing which lets you know where you're typing) is, at the current part of RichTextBox1. At the moment I'm using:
RichTextBox1.Text = RichTextBox1.Text + "The text I'm adding" If anyone could tell me the code to make it put "The text I'm adding" at your current cursor that'd be great.
2. I have a Save As button and a Save button. When you click Save As and save the file it works 100%, when you click Save and you haven't saved previously then it works 100%, but after you have saved the file and then click save it doesn't overwrite the file. Here's the code for Save:
[code]...
So if anyone can tell me the code that's needed so it will overwrite the current file 3. I have a FontDialog but I have no idea what the code is supposed to be to make RichTextBox1's font change after you click Okay in the FontDialog.
Im trying to keep a running total within a text box. The code I am using is
RunningTotal.Text = Txtbox1.Text + RunningTotal.Text
WHen I do this, RunningTotal.text only adds the content from txtbox1 onto the end, so I end up with something like " 1.50, 1.50".
Every time I hit Add, i just get another 1.5o added onto the end of the existing 1.50, 1.50.
I have a Save() function as shown below;
Code:
Public Function Save() As Boolean
Dim valid As Boolean = True
Dim Message As String = String.Empty
[Code].....
What I want to do is when The toolbarbutton1 is clicked it checks for the
Save () - if txtprojend.Text = "" then it displays the message. So far, it does that but then it closes the form. I don't want it to close the form unless the user adds text in txtprojend, as it is a mandatory field.
Is there any way to make the AppendAllText so that it startes a new line before it adds the text?

View 3 Repliesis there any way to get a numberupdown text to show the value "+" so if the value is a positive number then it adds the plus sign in front of the digits.
example:
2.00 would become +2.00
3.25 would be +3.25
as when its negative its
-2.00
-3.25
It already adds the negative value when its negative of course.

I'm having a problem with my global connection function. It used to be a readonly property but I changed it to a function because the code anaylsis engine was complaining about my property raising exceptions. The function is designed to take account of our offsite database mirroring system, so if it can't create a connection to the principal server it switches the connection string to the mirror server. This works fine in another project we have:
Public Shared Function Connection() As SqlConnection
If String.IsNullOrEmpty(ActiveConnectionString) = True Then
Throw New PropertyNotSetException("Cannot call Connection() before
[Code].....
i simple want to adapt . if connection is open we need to return true .else i need to return false .i have already adapt in c#. but we need to do the following way in vb.net .
public bool ConnectionTest(){
string server = Properties.Settings.Default.ServerName;
string catalog = Properties.Settings.Default.Catalog;

I'm having a problem creating a function for calculating an average. I need to divide the sum of a column of integers by the number of rows in that column. These integers are generated by a datediff command and their values are assigned to textboxes in a report. The results can only be whole numbers, no decimal points.
I'm pretty new to this so if this is an obvious question please excuse my ignorance. If you need any more information to address my question please let me know.

What I have is a simple sql storedprocedure that selects all employeedetails.And also another sql stored procedure that selects just a few columns from the employees table. On my frist page I am going to list all the employee names in a gridview and when they click the employee name it should take them to another page and show that employee's details. Seems like you have to use an object datasource to achieve this but is there an easier way to achieve creating a class that calls the 2 stored procedures that I have that i would be able to then link them with an objectdatsource?

i am going creating a simple function calculator, but I had to first do a design documentation proposal. I now have to update the project proposal with a storyboard or list of menu and screen items to delineate my proposed user screen and menus.aside from the calculator itself there will not be any menus.I also have to list any user data inputs and outputs my application will require and produce, which i assume i can put any numbers that the user inputs into the calculator and their results.
View 5 RepliesI am trying to create a Public Sub / Function that will allow me to pass certain variables into it and this will affect the output. e.g.
DIV ID = InfoDiv
CSS Class = "Warning"
LBInfoMsg.Text = "An Error has occured"
DIV Visibility = True or False
I would like to type something similar in the code behind page:
InfoMsg(InfoDiv, "warning", "An Error has Occurred", True)
Public Sub InfMsg(ByRef MyDIV As System.Web.UI.HtmlControls.HtmlGenericControl, ByRef CSS As System.Web.UI.WebControls.Style, ByVal strMessage As String)
strMessage = strMessage.Replace("'", "''")
MyDIV.Attributes.Add("Style", "warning")
MyDIV.Visible = "True"
End Sub
Alright so basically I have created a function so it can get the data and do the following things, etc
Public Function stats(ByVal texti As String, ByVal imageURL As String) As String
Label1.Text = weapontexti

End Function
I basically want to do something like that ^ and then be able to enter things (instead of writing lots and lots of code):This is what I want the function to do when I click a button:Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
weaponstats("Example Text", "images/etcimage.png")End Sub

Is it possible to create a routine in VB.NET with a name-based parameter array? The WebMethod attribute built into the framework is used exactly this way: WebMethod(BufferResponse:=False)
Specifically, I'd like to use it in a class' constructor. I'd like something similar to this:
New MyObject(id:=10,buffer:=True)
I'm not even sure what the terminology is for this kind of parameter list, so I can't even find it when searching.
