I'm not sure what is your question.

No problem other than my thinking I had linked you on the first go-around :)

I linked you on the article; this time it stuck.

Yup, got it working now. I poked around CP and couldn't find a solution which is why I asked the question; I may post my code as a tip here so others can find it. Thanks!

And, I don't think that later Frameworks can be used in place of earlier ones: a machine with the 4.0 Framework (VS 2010) cannot run an application written for the 2.0 Framework (VS 2005.) The Frameworks are not mutually exclusive, and you can have several on the same machine at the same time.

Open up your application in VS and double click the "My Project" icon in the Solution Explorer (or use the menu and use Project -> MyApp Properties). Select the Compile tab, then the Advanced Compile Options button in the lower left. A drop-down at the bottom of the form will tell you the framework your application links to. All target machines MUST have that framework to run. If you are using VS 2005, I believe it will default to Framework version 2.0. And yeah, I meant DLLs :D

This is the COM way to hide an application's window. It does not hide the application from Task Manager, which is what the person was asking about.

Clean and elegant.

I deleted my answer after copying your function and testing it in VS. Your problem seems to be with the algorithm itself.

You are welcome.

Your title says "web form" but your question is about "winform." These are different, which is it?

XML (eXtensible Mark-up Language) is just a text file that follows specific rules. It is very flexible; there were a few versions of Excel that used XML to store spreadsheets. A full tutorial would be well beyond what can be given as a quick answer, I'm afraid: you will have to do some research to find a solution that works best for you. As for "serialize" and "deserialize", those are just fancy words that mean "convert to and from a text format that can be moved between different types of data structures" including files.

Is the delay occuring when the page first loads, or after the button is clicked? At a glance, the issue is how long it takes your Javascript method to assemble the PDF and deliver it. Addressing that has nothing at all to do with ASP.Net.

Oops, my bad: I didn't notice that you had this flagged as SQL-CE. That version of SQL does not support programmability, so ignore what I wrote above. Given that, I would do what you already thought of and put each query and command in a separate function. Having only one instance where you are deleting a league will make sure that updates to your code are consistent (only one place to edit the delete command, rather than a dozen.)

I would recommend functions so that you can pass a result value back to the caller. Commands like delete or insert could return a boolean value indicating success, and queries could return a table object with your results. SQL-CE does support parameters, so I would still use those rather than hard-coding your values: it is a good habit to get into, and will probably have an efficiency benefit similar to what you see in a full feature SQL server.

That's what I thought, but figured I'd check. Thanks for the answer.

What is the actual problem you are having?

Are you trying to hide the cursor (the mouse pointer) or the caret (the blinking bar that indicates the current position within the text)? And why?

You cannot hide the cursor, although you can use the control's Cursor property to change the cursor that appears when the user hovers over the control. There really is no effective way to hide the caret, but you can use the control's ReadOnly property to make it... well, read only. That means the user cannot edit what is there.

Result is defined at the function level. Without an explicit assign at declaration, VB.Net automatically assigns it a value of False, making the assignment within the Try block redundant.

First, if I give it no explicit initial value, VB.Net will assign it a default value of False. Second, any change to a variable will persist within its scope. The variable is declared at the function level, so any change within the function scope will persist within the function scope, even if that change is made within a narrower scope like a Try...Catch block.

Your choice of framework will not make any difference. Even if you could interrupt the OS bootup -- and most operating systems will not let you do that -- the system will not be in any state capable of executing your code, because it has not finished booting.

The project is for a desktop content publisher app, where users unskilled with HTML can compose and edit rich text documents for our website. The app stores the content to a database along with various meta-data, and the content publishing infrastructure on the website picks up from there. This app replaces a much clumsier, less flexible web-based system (not my work) that has been in place for several years. The content database has over 1400 articles that must be backwards supported.

Given the lack of affordable WYSIWYG HTML editor components, I made the decision to use the System.Windows.Forms.WebBrowser component reset into editor mode.

I thought you were being facetious by saying the fault was with them being Microsoft Windows common controls. Then I read the Knowledge Base article and saw that you quoted Microsoft itself. Five stars for making me shake my head at MS' cluelessness. And, of course, for your good answer.

If all you want is a list of open forms, you can use the MenuStrip, which you probably already have on the MDI (that and the StatusStrip are the typical exceptions to the "no controls on a MDI" rule.)

Add a top-level menu on your MenuStrip ("Windows" is the traditional label.) On the ToolStrip control, find the property MdiWindowListItem and put set it to the name of the "Windows" menu. Now, the operating system will keep track of the open child windows as menu items under "Windows", allowing the user to change from one form to another by selecting the desired form. It will even put a highlighted checkmark next to the active window. Because this is done at the bottom of the menu, you can add other menu items on "Window" as well, such as options to reorganize child forms to cascade or tile them horizontally or vertically. Keep in mind that the Text property of the child forms (the part that is displayed in the form's title bar) will be the text for its menu.

Brilliant, works like a charm. Many thanks!

That is the usual way, yes, but tampering with the browser's history without the user's consent is not considered legitimate. I believe several browsers have disabled this ability because it has been used maliciously.

The first thing to check is: are the line breaks you want being given to WBHTML in the first place? Try adding Debug.WriteLine(WBHTML.DocumentText) after the call to Navigate; it may be that the text box is faithfully displaying exactly what it is being given to display.

The idea will work on any page, but you will have to customize it to fit the data input boxes that are specific to that one page.

Why is it necessary to place the document IN a page? Why not just serve the document as a file?

D'oh! Yup, that works: COALESCE(RepCode, '') = COALESCE(@RepCode, ''). One of those solutions that is too obvious. Thanks.

My HTML code is a standard table.

Like I said, I can get the summaries for individual grids in each grid's footer. What I need is an aggregate sum of all the grids elsewhere on the page.

So your question is about SQL and database management, not ASP.Net. You may want to change the tags on your question, then: you will likely get a more meaningful response when people know what you are asking about.

Compatible to what? The pointer, or the value being pointed to? Also, I'm pretty sure that VB.Net does not have UCHAR or C style pointers.

Trick question: if you are eliminating numbers that have already been selected, then by definition you are not selecting random numbers.

My apologies. I had to do this very same problem in one my early programming classes. Knee-jerk reaction, sorry :-)

I didn't realize this was possible: I've been soaking in the Framework too long. Thanks.

My understanding is that the API changes the system metrics and so would change every scroll bar, not just the control. It has been a very long time since I have done any API stuff, though.

I'm not sure why, but manually adding the MIME type to the new site's root web.config did the trick; it is nowhere to be found on the old site. Many thanks.

That was actually the first thing I checked: I have custom HTTP filters for delivering PDF and a few other document types. Neither the old nor the new servers have references for XFDF, and yet the old server delivers them up with nary a complaint. That's why I'm so frustrated.

Yup, this is my preferred solution. I believe it has the added advantage of protecting against injection attacks.

That's what I thought would be the case, thanks for the information.

I looked into that, too. This site does not have AJAX installed currently, and it will be shutting down within three months anyway. The new site is Windows 2008, which supports MaintainsScrollPositionOnPostback and makes my question moot. I was hoping there might be some kind of quick fix, but if I have to say "it will be fixed in the new version of the site," I can.

That's what I was afraid of. It makes sense to generate a guaranteed unique id when merging pages, but it's a (redacted) nuisance. Unfortunately, none of the solutions mentioned in your link offer anything I can implement. Thanks for the info.

I have to agree with digital man and the others. This is a matter of contract law, which is very complex in most countries. GPrime69 and others in the same situation can end up with a lot of grief if they don't get proper advice, I've seen it happen far too many times.

Follow up: Turning on tracing and using HttpContext.Trace.Write to output checkpoints showed that my custom GetUser function was getting called as much as 14 times (!!) every page call, not counting a DispatchLink control that retrieved user information and rendered according to permissions; some pages had dozens of DispatchLink controls. The fix was to cache the data rather than retrieving it each time. The control was rewritten to use that cache. The site is running much quicker, thanks again.

Ayup, you're running two for two. After enabling the trace, I found out that the problem was all in the rendering. Poking at the code behind the scenes indicated the GetUser method from my custom MembershipProvider. I will focus on getting that optimized and figuring out why it is so bloody slow on this one server. Thanks again.

Excellent, thank you. I will look those over when I get back to the office tomorrow.

The two sites are on different servers, and the styling is different. Images and page content are identical. Both sites are being accessed on the same desktop computer side by side. The lag occurs even when there is no database access, just serving up a static page.

Many thanks! Request.Filter does the trick, and I'm writing out my solution as an article.

That is a very intruiging idea, thanks. Never heard of that property before, and the BeginRequest thing looks interesting.

And why am I trying to explain these things to two platinum members? :doh:

A lot of CP contributors do not have English as their primary language, and it can show. I've seen (and sometimes made) edits to correct misspellings and grammar, fix punctuation and otherwise make questions, answers and articles easier to understand. Like any power, though, the ability to edit can be abused, which is why revision history is publicly available.

@Henry - If an answer or article has been edited, there will be a link where you can look up the revision history: note the "Revision 3" link underneath Yusuf's answer. Malicious edits and deletions tend to be caught quickly.

Yup, that works! Thanks.

I would agree, with the additional advantages of reuse and flexibility. A single file can service the whole site, or you can break it up into a file for structure and one or more for colors. You can also create separate files that will be used depending on the user's browser, allowing you to move all of the IE 6 quirks into one document, Opera quirks into another, etc.

It would be helpful to see what the actual error message is. My first thought is that the image file is in use from something else in the app.

Do you have any suggestions for how to create a list of persistable, displayable data? That is what I need; it doesn't have to be a ListBox control.

Added some code to my question. Hope it helps.

Problem solved with the ingestion of extra caffeine and the use of an OutputCache directive. Thanks anyway.

Nope. With or without the query string, I am passing the exact same same value into GenerateData, and the exact same document is being passed back out. The ONLY difference between using and not using the query string is the existence of the query string itself.

Seeing the actual text of the error would be helpful. Is the data conversion problem occuring in one of the cmd.Parameters.Add statements, or when you execute the INSERT?

I'm sure such code exists. Do you have a question?

The test site is on a different server entirely, one that sits inside our firewall. Other than that, the hardware is identical to the live server.

Thanks for the suggestion, but it didn't work. I used SSLDiag to create a temporary certificate (MakeCert has been memory-holed, apparently) and now the test site is running on SSL, despite much pissing and moaning from IE8. I ran through the tests and... still not getting authenticated. But, at least I've gotten rid of one more variable, thank you for that.

That would have been my first choice, but I haven't been able to find out how to do that for a website (desktop apps and the assemblies running on the website, that I can do.) But there is nothing in my custom code that relies on whether the site is accessed by http or https, so I don't think that is the problem.

If TextBox2 holds the domain that you are looking up, then why would you be passing TextBox1.Text? Also, if the value passed to GetHostByName is not a valid, registered domain, you will get a socket exception: make sure that you are entering a valid value for testing.

I don't think you read my question correctly.

I have some text -- say, a list of the rules for creating passwords -- that is used on several different pages. Rather than have this text actually written on different pages, I create a static text file and include it into the page. This way, I have a single file that can be updated and I eliminate the risk that different pages will drift out of synch.

My question is about the best way in ASP.Net to include that static text file in my pages.

Eh, slow day at work.

The problem with resource strings is that, you will need to rewrite your application when -- not if -- that data changes. I'm not sure how it would affect performance, as I've never tried that approach.

Who is this "you" of whom you speak? If you are asking about a specific article, you should put your question in the comments section of that article.

That shouldn't be a problem, as the extended text gets used as both the anchor's title attribute and (in some cases) a label with a description after the link. Carriage returns should work fine in both those situations. Thanks!

Added: Works perfectly. The line breaks are used in the text, but that doesn't cause any problems; I can trim them out in my web control if I want to be picky. Thanks again.

When I responded 4 hours ago, the question was quite different.

My apologies for not responding sooner ([censored] job.) Thanks, this is exactly what I was looking for.

I expect that the problem is in the regular expression; it would be helpful to have that.

Excellent, that is what I was hoping to hear. Thanks for the response.

Ah! So if the section is encrypted and I change a value, the configuration manager will automatically encrypt it? That is exactly what I wanted to verify, thanks.
