i have to port some projects to .net and of course rebuild some custom controls i made over the years.I have a control based on a simple panel and doing some drawing stuff on it.When the control is thrown on a form, i just want to draw a text with the controls name (<GroupPanel1>).But accessing the controls <Name> property always returns me an empty string.In the designer the control is named correct with <GroupPanel1>.
View 5 RepliesI need some of my initialization code to be blocked off if I am in Design Mode. This code is ran in the new method of the form, so it runs before the DesignTime Property can be set. Is there, or is there a way to setup, a compiler constant which indicates whether or not you are in Design Time. The Debug Constant doesn't work because when I run the application in Debug mode I want it to run
View 14 RepliesOn my custom control I've added a Property 'DisplayMode' that, at run time, does a great job of showing or hiding different sets of the standard controls. But, at design time - no matter what I seem to do, my control shows all of the child controls associated with it

Does anyone use or has anyone used the NetSpell spellchecker control by loresoft in a vb.net program? It was used in a program at work that originally was written in vb.net 2003 or 2005, but now has been upgraded to vb 2010.
When doing a spell check, there's a Save/Edit button for making edits and saving them. This apparently worked in previous versions of visual studio but it crashes the program in vs 2010. If anyone has used this control and has any information on why parts of it may not work or what could fix the Save/Edit function from crashing,
On visual studio how do you go about using tab control?I think I made a bit of a mistake in building a form first but now I want to move some of the features of it onto a second tab.I've implimented tab control with two boxes and figured out how to rename them but how do I decide which features show up when each tab is pressed?

View 2 RepliesI've making a program that must crop 20 squares out of a larger image that is in a picturebox. Now I've created a Draggable rectangle control and set it's Background to transparent. This is working (kindof).
Now I have set my control to doublebuffered = true and it Removes tha annoying flicker.My problem is that doublebuffering creates a new problem. My control's parent is a picturebox with a large picture inside.When I move my control over the picture to select the area to be cropped it updates slowly I.E The control Is in a new area but it still displays the old area and then updates which is annoying.If you want to see for yourself create a new project with a picturebox with a Image inside with my Control as a child of the picturebox.
[Code]...
I have thought of possible solutions but they might well be much slower.#1 Copy the part of the picturebox that is under the control and paste it on my control.#2 Somehow eliminate the backcolor property thus eliminating the need to paint something over the control and only paint needed parts .
When I dispay data sets in a Datetable control. It started with showing the focus on first cell ( i.e. cell(0,0)). How can I set the initial focus to other cell (say cel(3,4))?
View 2 RepliesBasically, I have a form. It has two datetimepickers which both have the format of "dd MMMM yyyy hh:mm:ss"..However, I want to be able to do some calculations with them and return a format of: "ddd dd MMM yyyy HH:mm:ss" with the milliseconds but not sure how to show the milliseconds. And how to do the calculations..A date and time gets entered in the datetimepicker of "18 November 2010 02:59:07"And in the other one the data may be: "20 November 2010 01:59:07"..I want to be able to find the difference between them - including the milliseconds, seconds, minutes, hours, year, month and date. etc..I have looked through the internet however, nothing uses a datetimepicker [code]I currently have this, it returns the number of different fields, but not sure how I can convert this into a readable time/date.
View 1 RepliesI cannot tell you how disappointed I am in the vb.net Web Browser Control. It really seems very ill thought out and rushed.So; to my question! I have searched all over the place in an attempt to find the answer to this and from what I can see alot of individuals are suggesting that it is better to use the old web browser control from VB6. However, i'd like to try to avoid this.
View 3 RepliesI am currently working on a program for my class. The user puts in two numbers into two separate text boxes and then my program takes those numbers and puts them through several arithmetic equations such as sum, difference, product, etc and displays them in a listbox. I have that part of it done. Now I have to make it so the users can only enter numbers ranging from 1 to 10 in each listbox. If they enter anything besides that I need a message box to show up telling them to only enter numbers between 1 and 10.

I have some questions about the Windows.Forms.WebBrowser control.I have added this control to my project to be able to browse websites internally.First problem is that when I come into a webpage that contains JavaScript to open a new window, the control opens a new instance of iexplore.exe, tries to load the page in which the java script popup code initiated, but then prompts for authentication for a second time.Basically, I have to sign into one page to get to a listing of applications.I click on the application which in turn is just a URL to another page.The URL to the other page contains java script to open a new window.The new window opens in an iexplore.exe process, but re-directs me to the original sign in window instead of taking me to the correct site.If I do a msgbox on the cookie that is currently loaded, it displays my authentication information.How do I tell the new iexplore.exe processes to use the cookie that was stored in the webbrowser control?

View 1 RepliesI am writing a customized data acquisition application in VB2010. The maker of the data acquisition hardware has provided an ActiveX control that has methods, properties, and events that can be used to interface with the hardware device.My problem is that I'd like to reference the same control (ideally the same instance of the control) on multiple forms.
To begin, it is necessary to initialize the device, sending the control information like sample rate, number of channels, etc. Then you can use methods to start or stop getting data and read properties, like the number of samples taken, or an array of the
actual data. The device also provides events, like a DataReady event that fires when a certain number of samples have been taken, and a DeviceError event that fires if the device is not present.
My program will have several forms:
1) a main menu that opens on startup and that should initialize the unit and determine whether it is present.
2) a daily check form that will get values from the device to determine whether the electronics are good.
3) a test setup form that will get values from the device to zero (tare) the input channels.
4) a run test form that will acquire and process the actual test data.
If I include separate instances of the control on each form, I need to initialize and stop the control when the forms open and close. I started to build an interface class that the forms could share and that would deal with all of the methods, but I get tripped up trying to pass the control's events back to the form.

View 4 RepliesI need a control that will allow me to do a few things.
The control should be similar to Listview in detail mode, in that it lets me show numerous rows, each row with multiple columns. However, I want it editable in place... that is, the user can (if I let him) click on a column and change what is stored there.
The next thing I need to do is set a graphic in one column, text in another, a playback controller in a third, and a trackbar control in the fourth. Every row will look like that.
The final thing I need to do is be able to control how a row is painted... either the entire line or by putting a graphic image (like a button) in a column when it is not being edited.
Barring all of that, I can put all the controls I need into a single user control, then I need some listview-like control that will allow me to add that control to it.. and have it be operational.
