• Windows Forms Other version is already installed

  I get this error message running setup created by VS 2005 Setup and Deployment project. Setup asks to remove old version of the program and install new one after this. What can I change in the setup project to prevent this - I want to update existing application without removing it. I tried to set RemovePreviousVersions to true, change UpgradeCode - this doesn't help. After Phil's helpfull direction, here is what I found in experimentation .... It seems a good idea to keep the setup project version the same as the application version. However, I found they are incompatible with each other! The application version requires a format of 1.0.0.0, and will not let you leave off any of those segmen ...Show All

• Software Development for Windows Vista Pipes won't work with limited accounts

  I am using Named Pipes to commmunicate between a Windows Service and one or more client applications (depending on the number of users logged in). Everything works fine if the client app runs under a user with administrator rights. When it runs under a limited user account I get the ERROR_ACCESS_DENIED message when the client is trying to connect to the Pipe Server (created by the service). This is the code section generating the error message: hPipe = Win32API .CreateFile( pipeName, // pipe name GENERIC_READ | // read and write access GENERIC_WRITE, 0, // no sharing IntPtr .Zero, // default security attributes OPEN_EXISTING, // opens existing pipe 0, // default attributes IntPtr . ...Show All

• Visual Basic Reading binary (or any it seems) registry data in VB.NEt

  Hi all, I'm wondering how to enumarate a key, one that's binary into a string or other system.type in VB.NET. I created a similar app as an hta with vbscript, and it was a breeze using the GetBinaryValue method. This does not seem so prevelany in .net. The code I have so far is here (be nice, it's my first week doing visual basic!) What I'm doing is searching through the guid keys under the 'base' key and looking for the REG_BINARY keys that have the value '001f6700'; the location of loaded .pst files. Everytime i tried to use the GetValue method it would return the value, not the data, i.e. 001f6700.....argh. Any help is appreciated. Thanks!

• Windows Forms Default MSI Property Value for Merge Module

  I'm using VS 2005 SP1 to build an MSI deployment project which consumes a pre-existing MSM merge module. This merge module requires a property (e.g. a path name) to be set, but I don't want to present a UI to get this property value from the user - instead, I want to set a default value for this property in the MSI for the merge module to use (i.e. hard-code the property's value in the MSI file). Does anyone know if it is possible to set default property values in a VS 2005 Deployment Project, or do I have to resort to building the MSI then manually adding the property and its default value using Orca (that's Orca the MSI editor, not to be confused with Orcas the next version of VS!) Thanks in advance... :D ...Show All

• SQL Server Application roles and Module signing

  Hi, Am migrating my SQL 2000 legacy app to SQL2005 and am dealing with restrictions on the underlying system tables. Have taken advice that Granting VIEW state to all users is heavy handed (especially meta data access at SERVER level). Now looking at Module signing which is great. I can supply SP's which target the few System table/ information schema fields that I require. Now I Sign the Sp's cool, now I grant exec rights to the application role (doesn't work). Create a db role and put my users in it, okay grant role exec on Sp's (fine they work). However my application runs under an application role always, so my users rights are ignored and it appears that its only the users not the approles who can benefit from the module signing I ...Show All

• Visual Basic Serialport Help

  I am writing a class that talks to a controller I use in my lab. I send the controller a command and it gives a response. I wrote a routine that sends the command and receives the response. HOWEVER.... If I step though the code everything works great. If I run the code it runs too fast and misses the response from the controller. I don't want to poll the serial port to see if the response arrived as this consumes CPU time unnecessarily. What I want to do is to write the command to the controller then suspend the method until the DataReceived event or a timeout occurs, then continue my method. Any suggestions Thanks in advance!
