• jiggs ToolStripProgressBar and Cross-thread Calls !

  Hello, I have a problem with updating the progress bar's value. The problem appears in the following code void sexyDownloader_FileDownloadProgress(object sender, CodeProject.Downloader.DownloadEventArgs e) { this.toolStripProgressBarFileDownload.Value = e.PercentDone; } I have a file downloader class running on a backgroundWorker - another thread - that notifies the form of the file progress.

• Craig G Encrypted .msi file results in installation failure

  Why is this Is it a bug If I unencrypt the .msi file, the installation proceeds normally, otherwise I get failure message 2755. Looking in the installation log, I was able to find a "failed to open stream" error which may be at the root of this. Thank you, Stefan. However, this raises another issue: When I search on msdn using the keywords "installer encrypted msi", as I did when trying to research this problem, the kb page you reference does not come up as a hit. Is the KB excluded from searches by default This is a known problem, see http://support.microsoft.com/ kbid=834549 ...Show All

• p4Pratik Many to Many Relationship Viewers?

  I'm looking for a control (or a way to link multiple controls) to graphically and logically display table data with a many-to-many relationship with another table. Here's what I am thinking: Have a datagridview (listview, etc) on the left side of the form. Have a second datagridview (listview, etc) on the right side of the form. Display the entire table contents of each of your two tables in their respective grid controls. Now draw lines from rows in the control on the left to rows in the control on the right. Remember those test questions in school where you had to draw lines from terms on the left to definitions on the right That's what I want to see (except now have multiple lines eminating from the rows). I can't find any third party ...Show All

• BrettColeman Print Windows Forms using a scanned Image

  Good day. I have a Windows Form in C# 2005 that I want to print. I have a receipt(delivery Form) that i would like to fill in some values and print it out with the form. I have scanned the form into a jpg file, then I tried to set the background Image property of the winform to the image. However, the image appears very large, it won't display the exact size of the image which is about 5.5 w X 7.5 h inches . I also set the backgroundimage layout, setting it stretch and zoom will make the image quite smaller. And what command do i use to print the form. Also, there are some other forms and receipts that needs direct printing with winforms without using Crystal Reports. How Can i solve this kind of problem.. Any help would be greatly appre ...Show All

• Aleksandr Tokarev Repositioning Graphic Objects

  Hi, Background: I am sending four collections of simple graphic objects(lines,rectangles..polygons) to a printer (to represent four different scale views of a building). The paper size is initially A4, but may be required to be multiple A4 or A3 if the graphic objects do not fit. This is referred to as the page number/size escalation process. I am using the various graphic class transformation functions and it works well. So far, I don't draw the images to screen prior to printing. The challenge is optimally fit the four collections on the page so that more pages are only needed if every effort has been exhausted to fit the images at any particular level in the page escalation hierarchy. I could just assign a static po ...Show All

• rternier sample code for programmincally install the "correct version" of .net framework?

  Hi, I wrote a very simple window form app, all it has is a label and couple buttons. When I send to exe file to another machine, it pops the famous error message: The application failed to initialize properly (0xc0000135). Click on OK to terminiate the application. Then I learned, the target machine needs to have .net framework install and the version of the framework must match where my app was built. My question: Does anyone have sample code for my program to determine if the target machine has the correct version of .net framework installed, and if not then my program would automatically download from msdn and install for user...etc etc etc Or if there are better ways to handle it (such maybe using the deploy option from vs. ...Show All

• dakerson WYSIWYG Web Editor

  Hi All I'm looking to create an application which enables the user to create PHP/MySQL (and eventually ASP/MSSQL) driven websites with just a few simple steps. Part of the application will obviously be some kind of WYSIWYG Editor for the look and feel of the website. I know there are already quite a few open-source HTML editors out there, but I need to customise this quite a bit, and I also feel it would be a good exercise for me to improve my programming skills if I program it myself. What I need is someone to tell me roughly how to start off and what steps to take. I'm not asking for detailed descriptions of every little step (and I'm sure most of you out there don't have the time to give them). I'm assuming to write the c ...Show All

• nharendt Dataset Designer: "Unable to find connection MyConn (MySettings)1 for object 'MySettings'"
