I have the special cable from HP which permits USB pen-drives and some other USB equipment to be attached to the PDA. They show up as "Hard Disk" in File Explorer. Does anyone have any idea, please, why just one of my six Sandisk Cruzer pen-drives does not show up? The drive works fine on my...

I have a regular visitor to my website complaining that when he clicks on the usual url, Internet Explorer "won't let me in". It used to until recently but no longer does so. I haven't changed the coding so the problem must be his end, but getting some basic info from him is like wading through...

There must be something about IE8 I haven't cottoned on to yet. The private admin part of my website has a page for updating the MySQL database and uploading image files relating to the new entries. It leads on to a separate page using simple css, some moderately complex php (by my standards)...

The last three times I have started drafting a question here I've thought of the answer before I got to the end, so here's hoping. This has me baffled. I take a row of data out of the MySQL database and put it together into a string, like so: $details = $row[4] . ' ' . $row[5] . $row[6] . ' '...

I use html and php, with IE7. Every example for uploading files I have seen uses a form with an input type of "file" and a submit button. I have used this and it works well, but it adds an unnecessary stage to my work-flow. The name of the jpg file to be uploaded and the path to it are already...

I used to use Outlook Express. After my PC reset itself unexpectedly and the .pst file got corrupted, I followed MicroSoft's advice and upgraded to "Live Mail", which I have to say did an admirable job of reconstructing the mail file, something OE had refused to do. On shut-down OE used to ask...

Thank heavens for Tek-Tips. Corel no longer support version X, though you have to spend 30 minutes typing stuff into boxes before they tell you that. I wasn't aware that Tek Tips had a PSP Forum, but thanks to Google I do now, and can ask my simple questions of people who are actually prepared...

OK, it's a dumb question. Delphi 7 PE, WinXP. A procedure in my latest project declares a variable N as a String. The variable then gets its value from an index to another string, as in: N := String[25]; N then goes through a lot of processing until it's time to put it back where it came...

After many hours of searching in books and on the net, I can't find the answer to this simple question. Maybe I'm using the wrong keywords to search under? "Boolean" just brings up stuff about Boolean searches, and the word doesn't exist in this forum according to the search facility! I pull...

After many hours of searching in books and on the net, I can't find the answer to this simple question. Maybe I'm using the wrong keywords to search under? I pull out rows of data from my table in the usual way, ending up with the row I want to work with in array variable $row. The data are...

A very simple theoretical question, I hope. No code is necessary. If the result on the webpage is to be a concatenation of fields from a MySQL database, is it more efficient to use CONCAT in the MySQL query and retrieve a single item into the php result array, or to retrieve the fields...

Please forgive what's probably a basic query for all of you. And I don't know the correct terminology yet. I need to retrieve data from four tables into one php "$result" with one MySQL query. The tables are configured as follows: Images ImageID (primary key & the only unique field)...

I've read a lot of guidance about using PHP and MySQL and so far I'm successfully retrieving all sorts of complicated joined stuff from my tables. But the established way of retrieving data which is in all the guidance seems way over the top when all you want to do is retrieve a single column...

I have a website which needs to display photos to site visitors based on their selection from a table in my MySQL database, via a PHP form. I do not want them to have to provide a username and password to do this, the complication of a registration system is totally unnecessary. All the...

Delphi 7 personal edition, Win XP SP2. I have recently successfully installed "XLSReadWrite" into my Delphi system. This is a rather old but fast and functional widget for reading/writing Excel files, and it must be properly installed because all the demos work, even the new stand-alone test...

I use Delphi 7 in Win XP SP2. One of my programs loads a text file into a StringList for processing. After 7 months of daily files, the external provider has somehow started producing files where each line ends with not one but two carriage returns and a linefeed. When viewed in NotePad the...

This one has me baffled. I use Delphi 7 Personal Edition. The Delphi Help says of IndexOfName: "Returns the position of the first name-value pair with the specified name. ... Call IndexOfName to locate the first occurrence of a name-value pair where the name part is equal to the Name parameter...

Please bear with me, I only program occasionally - usually two new versions of Delphi come out between my programming stints! I'm using v7 now. I have a simple but long for loop, which goes like this: for i := 1 to StrList.Count - 1 do begin {(1) reads string i from a stringlist - this...
