Dear all I'm trying to track down the name/existence of software that I used in 1999 to 'write' a financial reporting system - it was a curious mix of spreadsheet with programming capability... Would any of you know about this? Its name was similar (-ish) to Visual Basic, but it wasn't VB itself... The way I was asked to use it was to collate financially reported information from a series of European entities and then present them in a specific format for the client. The client was Synstar (pan European disaster recovery computing service), since taken over by HP. The …

I have a Dell and I'm running 8.1. I can't download or upgrade anything. After a couple of days my email wont work and the internet slows down to a standstill. I usually restart my computer and it wont start. I keep hitting the reset button for about 15 minutes until it finally catches. A huge thank you for any help with my problems. Everything is backed up and was wondering--even though I don't want to should I upgrade to windows 10. Can I even still do this for free??? Here is my log from my computer.

I understand, I have to calculate number of steps used in every stage. My problem is: how can I know, how many steps used in every stage, for example, n, n/2, n^2... Computational problem L: L(x)=1, if input date x is in the form y#z, where y and z are strings of the same length. The strings consist of the symbols a and b.

Hello everyone. Despite my boot order set to Windows Secure Boot (USB last) and UEFI, when I turn my computer on it hangs at loading until I disconnect all USB external devices. When the computer tries to go to sleep mode, the screen goes black and I can hear the computer trying to go to sleep mode and coming back (the screen remains black) while the power light stays solid blue and I can not bring the screen back on. It is after I unplug all USB devices that the power light switches to blinking orange and then I can …

I'm trying to write a function that will draw a right triangle that will ascend and then descend after the max height is reached. It is to be drawn using the asterisk symbol. I'm fairly new to recursion and that is the primary method I need to use to solve this problem. Any guidance or critique to my code would be appreciative. I can only edit the code that is marked TODO. ![Desktop_3-25-2019_12-16-42_PM-239.png](/attachments/large/4/b3aa4c2ae8f713c4d688654b049bc59b.png) // File: main.cpp #include <iostream> #include <fstream> #include <iomanip> using namespace std; int recursiveCount = 0; void triangle(const char drawChar, const int maxHeight, const int currentHeight); int …

Hello all, So last night I decided to add an older HDD into my new desktop to... well add more storage since games now-a-days are HUGE, and I was running out on my current 2 drives (main SSD with Windows 10, and an HDD). I didn't realize that the older HDD had Windows 7 installed on it (completely forgot that it was there...), which I installed into a SATA3 slot 0 (other 2 were on slots 2 and 3 respectively because the graphics card made it difficult to use slots 0 and 1). After booting it up, it started chkdsk …

Hello, I'm trying to create an environment variable by parsing a very ugly XML file returned by a curl command. Contained in the XML is a MAC address that I'm trying to use FINDSTR to find and then SET it as an environment variable for the local user. Here is a snippet of the XML that the curl command returns: <CameraStatusModel xmlns="***URL contains sensitive info, so removed it***"> <CameraStatusModel.ActiveCamera> <RectilinearCameraDeviceModel CompassHeading="0" IsConfigured="False" MACAddress="00:30:53:27:27:f4" Make="Basler" Name=""> <RectilinearCameraDeviceModel.CalibrationMask> <RectilinearCalibrationMaskModel Id="a1155f60-2900-442c-82a8-6c00dadbf243" Length="0" Width="0" ></RectilinearCalibrationMaskModel> I think the FINDSTR command I need to use is: `FINDSTR /r [a-z0-9]{2}:[a-z0-9]{2}:[a-z0-9]{2}:[a-z0-9]{2}:[a-z0-9]{2}:[a-z0-9]{2} c:\Users\<MyUsername>\Desktop\sandbox\output.txt`.

Yesterday I followed a thread trying to learn to lock file folders using the cacls in the command window. I thought I'd use the temp file folder as my target, thinking that it was the most innocent folder I had. I was able to lock it, but now I can't unlock it. Here is the code that I used to lock it: cacls %temp% /G %username%:R it asked me: Are you sure <Y/N> I replied Y, and it returned "processed dir: C:\DPCUME~1\HASLAM~4.AFT\LOCALS~1\Temp I could confirm that I was unable to save anything to the temp folder.
