• Windows 7 - Windows Update won't update

  - by StickFigs

  I'm trying to update my Windows 7 Professional 32-bit edition and when I try to tell Windows Update to scan for updates it failed with the error code 0x80096001. I checked out WindowsUpdate.log and it appears this is the problem: Validating signature for C:\Windows\SoftwareDistribution\WuRedir\9482F4B4-E343-43B6-B170-9A65BC822C77\muv4wuredir.cab: WARNING: Error: 0x80096001 when verifying trust for C:\Windows\SoftwareDistribution\WuRedir\9482F4B4-E343-43B6-B170-9A65BC822C77\muv4wuredir.cab WARNING: Digital Signatures on file C:\Windows\SoftwareDistribution\WuRedir\9482F4B4-E343-43B6-B170-9A65BC822C77\muv4wuredir.cab are not trusted: Error 0x80096001 How can I go about fixing this? It looks like it's just this one (corrupted?) file that's causing the problem. Thanks! UPDATE: Upon inspecting the file mentioned in the error message it appears that the file does not exist! What does this mean and how do I get it back? UPDATE 2: Ok it appears that the file in question appears only for a split second when Windows Updating is trying to search (but fails) to find updates. So I guess the problem doesn't have to do with the file specifically then.

• Automating Nightly Build Installation?

  - by StickFigs

  Every night a new build of my program is made and copied to a /Builds/ folder. I have a Windows machine that I want to have uninstall the program then install the latest version of the program from the /Builds/ folder. Currently the build results in two separate setup.exe files which are InstallShield installation wizard executables. I want this to happen every night after the build finishes: Uninstall first component. Uninstall second component. Install newest build of first component using setup.exe. Install newest build of second component using setup.exe. I figured that there probably already exists a software solution for automating installations like this. Are there any software solutions out there than can do what I need? Preferrably for free?

• Get index of nth occurrence of char in a string

  - by StickFigs

  I'm trying to make a function that returns the index of the Nth occurrence of a given char in a string. Here is my attempt: private int IndexOfNth(string str, char c, int n) { int index = str.IndexOf(c) + 1; if (index >= 0) { string temp = str.Substring(index, str.Length - index); for (int j = 1; j < n; j++) { index = temp.IndexOf(c) + 1; if (index < 0) { return -1; } temp = temp.Substring(index, temp.Length - index); } index = index + (str.Length); } return index; } This should find the first occurrence, chop off that front part of the string, find the first occurrence from the new substring, and on and on until it gets the index of the nth occurrence. However I failed to consider how the index of the final substring is going to be offset from the original actual index in the original string. How do I make this work? Also as a side question, if I want the char to be the tab character do I pass this function '\t' or what?
