DWF Viewer Crashes WebBrowser Control?
Nov 9, 2011
I have a strange issue with a Web Browser control on a form. The application I made is nothing more than a form with a tab container and each tab navigates to an intranet web page. One of the tabs is directed to a documentation site that allows users to view machine documentation (parts lists, PDF files, electrical/hydraulic prints, etc.). Everything works fine on XP, but on 7, the application crashes when trying to view electrical prints (DWF files). If the site is opened in internet explorer, the DWF files open as intended. The computers have the Autodesk DWF viewer plugin installed (V 6.0). I need to somehow direct my application to the DWF plugin?

We have a .NET Winforms application that hosts the Crystal Reports Viewer control (Version XI). It works well for the most part but when an export of data from the viewer is performed the application will crash on exit and in unmanaged code. The error message is not very useful and just says that an incorrect memory location was accessed. No other info such a specific DLL etc. is provided.
This only happens after the viewer is used to export a report to CSV, XML etc. My guess is that at some point in the export process Crystal creates a resource that attempts an action on shut down to a parent window (perhaps) that no longer exists.I've seen a number of memory leak and shut down issues with Crystal but this one's new. Has anyone seen it and come up with a workaround or has ideas for workarounds?So far we've tried explicitly disposing of all crystal-related objects, setting to null and even setting a Thread.Sleep cycle on shut down to "give Crystal time to clean up."
Update:The crash happens only on shut down (so not immediate)All export formats work
All export files are created properly
CR is installed on the same machine as the hosting .NET app not sure about exporting from the IDE... is that even possible?

he Just trying to figure out some mouse Control Functions, I got it sort of working.the program run's, and does what it's meant to do, but then it crashes with a PInvokeStackImbalance error. [code] I just shortened the Code because there were a lot of Sub's that were not part of the problem, now it's easier to read.and If you haven't seen my other post it's NET version 4.0 in VS 2010

I've created a form that has a timer control. When this form loads it counts down before running a procedure. Simple.
Now I want to subclass this form in a new VB.NET project to so that another form inherits this form (an it's timer functionality) and runs a different procedure on this new form.My problem is that when I create the form in my new project the timer from the parent form seems to be running and when it's time is up it runs and code and crashes the VS environment.
I've searched high and low but have only found references to making sure the timer is disabled at design time. I've done this on the parent form but in this parent form's Load event the timer is enabled.... the purpose of the form. So when the child form loads it is enabling the timer. How can I work around this? Can I enable the timer from the child form? Timer is not visible when the child form loads so how do I manipulate it?

I'm creating a Windows Service that needs to print a report. Obviously a service app does not have a user interface. Is there a way I can print my report definition (RDLC) programatically or do I absolutely have to have the Report Viewer control on a form?

The company that I work for is not so much sacred of new technology they just seem to let things slip, you know the type, "It worked 5/6+ years ago so I don't see why we should change it"Despite this I have managed by hook or by crook to get an installation of SQL server 2008R2 to develop on which has the reporting services. Excellent I think, I can finally start moving some of the access applications to VB.net and use SSRS to provide some embedded reports, everyone is happy.But not so fast, it turns out the standard build of desktop here only has .net1.1. I have managed to dust off a copy of visual studio 2003 (The last edition that could target 1.1) and built a few little tests to check DB connectivity. The problem I am having is the report viewer control is only available in .net2.0 and above.So what options do I have for displaying my SSRS reports in a VB.net1.1 thick client application?
Before anyone asks the following options are out
Going anything web based (Farrrrrrrrrr too modern for the company + no web server)
Upgrading to a version of .net released after George Bush the 2nd lost an election but still became president

In onw of our application, we have some reports that need very specific margins that are dependant of the printer the user have. It is used to print into preformated paper with blanks to fill and depending of the printer, the printing is off by some margins. To make things worse, we don't actually control what printer is used because it is not an internal application.
The only solution I could think of is to let the user configure the margins somehow. I though I could just dinamycally change the report margins like I did with datasources and actual report ( I have one control that is used to display every reports from my application and it works alright), but I can't seem to find that damn property to do so. There is a margin property on the report viewer but it's for the form display so it doesn't cut it.What I was thinking to do is to define the margins before the user loads the report, i.e. when he clicks on the report button, I load the report, set the margins (or vice-versa is necessary) and then display it.
Before someone mention it, I know the user can, once the report is loaded, change the page setup to fit his needs, but this has two drawbakcs. First one is that it is not saved each time and I need it to be 'saveable' and by users. The second one is that Report viewer seems to have some bugs when the regional setting aren't set to what it's expecting and we can't force the users to changes their setting to accomodate one application.

I have a vb.net project containing the report viewer control that has a dataset bound to it. I have designed a letter in report viewer and need to highlight a few words by bolding and underlining the words. Can this be done? All I seem to be able to do is bold the textbox control, but then every text that resides in the text box will be bold and underlined. I cannot create a static label because the names may increase or decrease in size as well.

Im looking for an image viewer that supports most types of image formats, including PDFs, and has the ability to rotate/zoom, and draw on an image. I've been looking but to no avail. Does anyone have any suggestions on the best way of going about modifying a control so that I would have these features? The main problem that I am running into is the lack of the ability to draw on an image. Im still sort of a newbie to .NET,

I am re-writing my old VB6 DXF viewer control in VB.NET Winforms. Attached is a picture of my testbed app. As we only need it to check parts that have been created to generate gcode for our laser it is limited to Points, Lines, Arcs, And Circles. It has Point, EndPoint, Centers, and Intersections snaps for all entities and combinations of entities. Measured output is displayed as Actual Point to Point plus Horizontal and vertical delta. Zoom Extents, Zoom Window, Pan and Mouse Wheel Zoom are fully functional. The last took a while to develop as I wanted the Zoom to be centered about the cursor position just as it is in Acad.

Can't get the report viewer to do anything at runtime.After watching the tutorial on MSDN, it seemed simple.But I can't reproduce it. The data configuration is straightforward and no errors occur. Dropped back to putting something static on the designer like lines, backcolor and textboxes. They disappear too. The runtime control is active, just blank

I have already posted this question on the "reporting services" forum and received no responses, so i thought i'd give it a try here.
SQL server 2005 SP3, VS 2005, vb.net, RV control.
When i add a background image to the page header, body and page footer, The rendering takes about one second per page. Without the background images, it renders about 25-50 pages per second. My report is a statement print report and has about 1500 pages.
Since it is the same image on each page, why does the server need to send that image over and over again to the report viewer control?
In vb.net i have the Report Viewer control and i bring up a report in normal viewing mode. when i click on the print layout mode, or have that mode set up to be the default mode, It takes forever when i have a background image and virtually no time for the same report without the images. The images are gifs about 5 or 6k each. I have chosen to embed the image into the report.
How do i optimize the usage of background images so they do not interfere with the rendering speed? Or at least minimalize the slowdown.
[EDIT:] I have discovered that if i render it to PDF and open the PDF and page through the report, it is much much faster. In other words if i choose to render to 'printlayout', it is say 25 times slower than when i render it to default, and about 20 times slower then if i render it to PDF. And the PDF contains exact rendering for all pages, exactly the same rendering as the print layout mode generates.

I am currently updating an application from Vs2005 to Vs2010. I'm having an issue rendering the report viewer (using SSRS 2k5) in the browser.When the report is loaded, I get bombarded with popups that say "Unable to load control". After all the popups, the report eventually load (thank god for firefox's prevent additional popup checkbox), yet none of the buttons work (each button causes the popup).
here is my code
html
<asp:Button ID="test" runat="server" Text="Run Report" />
<rsweb:ReportViewer ID="ReportViewer1" Width="700" Height="900" runat="server" />

I am writing a few web based apps which will require a webbrowser extension. I have already used the IE webbrowser control that uses the trident web rendering engine. I believe this is MSHTML.DLL? Anyway, some of the users of my programs have complained of a few things. Particularily,
1. It seems to be a slow browser, at least compared to other rendering engines out there (webkit and gecko are 2 known ones).
2. On the developer side, it seems to be low in features. The features are sufficient in most cases, but there are some "special" things that I need.
3. It has VERY low HTML (and especially HTML5) compliance.
My question is, how much work would it take to use a different engine (such as webkit .net, which I HAVE heard of) and be able to distribute it easily. Or, if you guys feel ambitious, we could try writing a brand new engine ourselves. I know how big of a job it is, and frankly, I have no clue where to begin. I would just like your thoughts and opinions on the matter.

Working with a form that has a menu, toolstrip and Crystal Viewer control. I cannot seem to get the viewer to maximize properly without hiding the toolbar of the Crystal Control behind the menu and toolstrip. I've played with the options of Dock and Alignment, as well as autosize and I just can't get it to work.So do I need to handle the sizing myself to do this and position the control where I need it?

I have a regular application form with a WebBrowser control.I have strung together a .htm file (from a regular text file) which I then assign to the WebBrowser control. In the html file, I have filenames mentioned.I am trying to string together the html in such a way as to give a clickable link or button that will parse into html and open the corresponding file in another WebBrowser control in VB.I have tried using VBScript and JavaScript to put a button in the html.As long as the function or sub I call is also in the same html document, it works, but I really need to transfer the control back into visual basic where I can do the heavy lifting I need to.can I just not do this as a regular VB application? Any way to do it without adding the complication of requiring ActiveX?

So I've got a button that adds a tab using the tabcontrol object.

How would I add a webbrowser to that since i dont know what the tab page # of it will be specifically?
Each tab will have the same components, but might goto a different url.
