I am trying to make a basic "paint" like form for one of my programs.I would like it to be like a function, where I put the input in, the user changes it, and when the user is done, it returns the changed picture.I know how to draw the picture and then draw lines, dots, whatever where the user clicks, but I don't know how to do some of the features like: text, color picker, zoom, erase, select (copy and pasting parts of the image) , and fill. I also don't really want to have a color picker dialog open ever time that the user wants to change color.

I am now programming using VB2005, and I have a need of a simple drawing tool inside my program. I am wondering if I can embed MS Paint into a VB2005 program?

View 2 RepliesI am trying to create a simple paint program with radio buttons to change colors and size of the brush and draw within a panel on my form(VB 2008 Express).I cannot get the buttons to work. What do I need to put in the radion button event to change brush color and then also brush size? Following is the code I have so far, with nothing in the radio button events, because everything I try does not work.

I'd like to create a user-defined data type in VB.NET but don't know how to do it.Ta say there's a variable to control the action of a timer control. The possible actions would be "no action", "run timer", and "stop timer." I could do this with an integer (e.g. 0=no action, 1=run timer, 2=stop timer), but I'd rather create a data type so that the options are more explanatory than a simple integer. Like so....
Private Timer_Action as MyDataType
Timer_Action=MyDataType.RunTimer

I was playing with vb 2008 express and i created a function with no return type. Basically what it does is i specify a table name and a column name and it returns the value within but it doesn't type it until it gets to the calling variables type. So i have on function that i can use across all my tables.
Eg:
dim mydate as date = getvalue("tblSRs", "datelogged")
msgbox (mydate)
dim desc as String = getvalue("tblSRs", "description")
msgbox(desc)
Both return the correct values. were you always able to leave the typecasting till the end and whats the major downfall?
I have problem in calling DLL file in VB.Net that I had Created it in C++... it give me this error message: "An unhandled exception of type 'System.EntryPointNotFoundException' occurred in test_dll_1.exe. Additional information: Unable to find an entry point named 'add_1' in DLL 't1.dll'."

I have two classes:
Public Class Subscribing

Is there a more elegant way to add do this? One class would suffice, but since the Add methods have different arguments, then one really wouldn't work.

View 2 RepliesI'm looking for a library compatible with microsoft.net framework that allows the creation and verification of XAdES signatures (XAdES, XAdES-C, XAdES-XL, etc...).It is important that the library enable the programmer to choose:
1.- Type of certificate to use in the signature process (PFX file, Windows centralized store, SmartCard)
2.- CRL to validate the certificate.
3.- Possibility to include Time stamping on the signature.
4.- Possibility to include OCSP response on the signature.
All I found are libraries in Java, but have not found any libraries in .NET.
Do you really need this keyword to overload methods? What is the difference between using the overloads keyword vs. just having different method signatures?

I added a table to my program and it generated two errors and not it will not build. I have added quite a few tables and this has never happened before. The reeors are:
1. public sub new ' has multiple definitions with identical signatures
2. 'Protected Overrides Sub OnCreateMainForm()' has multiple definitions with identical signatures.
I have deleted the table that I added and tried undoing everything having to do with it but nothing works.
I have created a program in vb.net, something like a inventory system. a simple one.. my only problem is, how can i add a configuration option where my user can select which server he will use for the database?

I have a number of unrelated subs and functions that do various things on my server (e.g. Lighting control, data caching, server maintenance, etc). They are all in various classes which I have coalesced into a single solution.My goal is to create a single, simple interface which each of these disparate classes can be integrated and called from a command line interface. Instead of hard-coding a longish case statement which parses arguments and passes them to the various subs, I wanted to make a generic class which can be instantiated with a minimum of information and put into a data structure. Ideally, adding a new function would involve:
1.) Providing the function pointer (Delegate). The delegates will have various signatures. This is the crux of the question.
2.) Providing ancillary info such as the command-line callable name, number of arguments, argument types, etc.
I have a 100% working class called "node" which is basically a hierarchical tree of node instances. I can use this to simply organize function calls in related branches. All is working quite well.NodeFunctionDelegate(ByVal args As String) As String.The node takes the arguments passed to it by the command line and sends it as the "args" string as comma-separated. The delegate function then needs to know how to split up these comma-separated values, type them, tryparse them and etc. It then must return some string.It works, but it involves writing a middle-man function stub which can receive the argument string from the node class, do the parsing and type checking, and then call the destination function.My goal is to eliminate this trivial middle-man function. The problem is, I can't figure out how to create a variable-signature delegate for the node class.
Visual Basic gave me these errors:

I am having a problem setting up automated email signatures for a company through VBScript. Everything works fine apart from the rich text file creation. In this section for some reason a double underscore (__) always appears at the end of the e-mail signature when a user has their outlook set up for rich text. As you can see the script creates the signature in all the file formats needed.
