• mcmarquez 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

• Pradeep Gupta Launch Condition Haze

  Hi. how we could reinstall the installation itself after a launch condition setup In a Visual Studio 2005 setup, use the Prerequisites button on the properties to build a setup.exe that will install the framework then launch your MSI file. The MSI itself also has a check for the framework, but that will be satisfied and the MSI file will just install. You probably don't mean the ".net framework sdk". You mean the redistributable for apps to run, not the SDK fopr developers to use. I think you are going to need to explain for fully what you are trying to achieve. Your current description is not very detailed and less likely to get a positive response without more details. ...Show All

• Lewis Horowitz Displaying Database information in ListView

  I created an address like database with first and last names and include a photo location in the database. Now I want to use ListView to display the photo and name of each row(person) in my database, but I don't know how to retrieve a string from a single cell in my database. can anyone help what you may be after is databinding, which is easily done in this case.

• Evan Mulawski Saving contents of a graphics

  Is it possible to save (and restore) the contents of a graphics Graphics.Save only seems to save the properties, such as transfromations, but not the contents. See the example in Visual Studio help under Graphics.Save. My aim is to construct a vertical line cursor on a graph and move it with the mouse. I know how to get the mouse position, but in order to move it I need to restore the picture to what it was before the cursor was added, then add the new one. Thank you. I will try that. (I need to translate it into C#, but I think I know how to do that.) Paint your graphic into a bitmap, then render the bitmap with Graphic.DrawImage in the Paint event handler.

• JohnGBunch Help with NumericUpDown

  Hi all, I hope someone can help me with this. I have a calculated result that i send to a numericUpDown. The value inserted in the first NumericUpDown is then collected and prcessed further. The reason why I'm using the numericupdown is that the reults will be compared to a "real value" and the user should be able to correct this since the result will be further processed. My question is how can I capture the correction, i.e. if the calculated value is 200 but the user correct it by using the up and down buttons to let's say 203 I want to get the value 3.
