Limiting The Size Of A RTB?

Jan 30, 2011

My application allows the user to enter text into a RTB including all the various text font, size, etc changes. The user then prints that data onto a label. I got from my previous posts, I can print that on my label Each sheet has four labels, 3x5 inches. I print landscape and adjust margins to select the right label.But I want to limit the amount of text the usr can enter to the amount that will fit on the label. In essence, what I would like the user to see is a virtual label on the screen that they can type data into and get exactly the same formatting on the label when they print it.

I found several (mostly old) articles about linking the RTB to the printer, but nothing on how to set and limit the size of the RTB to the exact size of the label.

Limiting Array Size Through Class?

May 29, 2009

Is it possible to have a UD Class that can limit how big it can grow as an array?

for example:dim var(10) as class this would throw an exception cause the class will only grow up to 5 elements.dim var(4) as class valid cause it is under the 5 element rule dim var(4, 10) as class invalid cause the 2nd dimension is above the 5 element rule. (would throw exception)

Limiting Access To A DLL In .NET

Feb 12, 2010

I write in-house software for a company. I always want to leverage OOP techniques as best as I can. In this thinking, I want to create a Data Access Layer (DAL) isolated in its own .DLL. What can I do to limit the access of the DAL DLL to only my business logic layer DLL? The last thing I need is someone in the company with a little programming knowledge plus access to the system (via Active Directory) to install .NET Express, reference my .DLL, and start firing off data access code outside of the real system. Are there any .NET mechanisms I can employ to limit a DLL to be used only by a pre-selected host application/DLL?

Limiting FPS To Screen Refresh?

Apr 19, 2009

I have made a game (real time strategy) and it is running rather fast on my 3 GHz quad 8800 GTX, namely, it runs around 200 FPS usually when there are like 80 units and tanks in a forest fighting.

I would like to limit the FPS. So far my limitation code is pretty buggy... it does limit, but wrongly:

Private Sub LoopGame()
Do While GameIsNotPaused
FPS += 1

[Code]....

Also, after I solve this weird issue, should I set the value to monitor's refresh value which is usually 60 Hz on LCDs? Or should I set it to 30 or what ?

Limiting Textbox To Numbers Only?

Feb 20, 2012

I've made a lot of progress on my project. Only question I have now is how do I limit a textbox to only allow users to input numbers and one decimal point? The point of the decimal point is to make it currency. So if the answer of my calculation is 56.56566 I only want it to be $56.57.

Sql - Meaningful String Limiting?

Oct 10, 2011

I've got rows in my table that contain text anywhere between 31 character and 281 characters long.Rather than display all this text in my table on my webpage, I'd like to limit this text to a few characters long so as to identify it to the user.What I've done is select left(ColumnName, 30) but this way is fairly ugly on the page as it cuts off the text in the middle of words.

Limiting A Text Changed Event?

Jun 11, 2009

I have an number of text boxes and comboboxes on different forms. I have textchanged events which trigger a msgbox if the user enters invalid data(i.e. the number they enter is to big or to small). Is their a simple way to make the program not call the textchanged event when the form is loaded and the boxes get their initial value? Second is their a way to make the textchanged only be triggered when the user enters data not when the program clears the boxes?

Limiting Values In An Object Property?

Dec 15, 2009

I have a class called Item which contains all the information about all parts, finished goods, in process parts (parts made on site), purchased parts, and raw materials.

I have a Bill of Materials table which has the following columns (reflected in the BOM class)

ParentItem
ChildItem
ChildItemQty

Parent Items can only be Items which have subcomponents.

Child Items can be parts that are made on site, purchased parts that are bought ready made from other companies, or raw materials used to make a part that is made on site.

Parent Items and child Items both inherit the Items class.

I will limit the Parent item class to only items that are in the parent column of the BOM table. I believe I can limit that by doing a quick look up on a view which only shows the parent items.

I will limit the Child Item Class to only items that are in the child column of the BOM table. Same method to limit it by doing a quick look up on a view that shows only the child items.

That way, an instance of the BOM class will have all the detail information about any of it's components available whenever I need them.

.net - Limiting The Mouse To A Form Without The Ability To Override?

Dec 29, 2009

So I am trying to make a program where the user is limited in moving the mouse to a form. I still want the user to see whats going on behind the form but not be able to click on anything but my form.

I tried using this

Avoid A Possible Hang By Limiting The Time A Method Is Allowed To Take?

Jul 6, 2011

I am using an external DLL (pdfsharp) to open (then manipulate) lots of PDF files. I use: Dim inputDocument = Pdf.IO.PdfReader.Open(PDFPath, IO.PdfDocumentOpenMode.ReadOnly) Problem is - it seems to hang on certain, rare files. I don't seem to get any timeout - it just hangs for hours on this line. We read thousands of files with this code, always on tiny files, so I was thinking that a quick workaround might be to somehow timeout if the this method takes more than a second or two. But I don't see a simple way to do this. I am hoping to avoid spinning up a worker thread.

Pattern For Limiting Number Of Simultaneous Asynchronous Calls?

Apr 9, 2010

I need to retrieve multiple objects from an external system. The external system supports multiple simultaneous requests (i.e. threads), but it is possible to flood the external system - therefore I want to be able to retrieve multiple objects asynchronously, but I want to be able to throttle the number of simultaneous async requests. i.e. I need to retrieve 100 items, but don't want to be retrieving more than 25 of them at once. When each request of the 25 completes, I want to trigger another retrieval, and once they are all complete I want to return all of the results in the order they were requested (i.e. there is no point returning the results until the entire call is returned). Are there any recommended patterns for this sort of thing?

If I remove Take(100), a single query to sent to Sql Server.So, how do I limit the number of rows returned, while preventing a new sub query being executed for each row?
