 | I think the problem lies here: [code] intValue = Convert.ToInt32(userInfo); userInfo += intValue; [/code] intValue has no value specified and you set userInfo to zero at the start. So you are really saying intValue = 0, userInfo += inValue (which is 0 += 0). I think you should be using …  |
| | Does that answer your question? ;) I have found that the answer is no, networking requires a different set of skills to programming. Knowledge of one might help you with the other to some degree but generally speaking there is no real cross over. Thats my opinion anyway. |
| | For things like comments and posts, which aren't actually files, you would simply store them in a database. For saving files you would want to set up a folder (or several) to house the files and then use a database to show what files are linked to which user. For … |
| | Sorry, is that code meant to simply insert the data the user entered in the text boxes into the database? For the second part of your question you need to use SQL to run a SELECT statement on the database, pulling out the record of one customer I assume, and … |

| | What have you done so far? Is it the SQL for the query you are having trouble with or the whole connection thing? For clarity, what is your table schema like? Are all three tables linked by the same foreign key? |

| | Coders and sys admin need a good working knowledge of databases. But programmers will need more SQL query style knowledge and seldom need replication, back up, admin style knowledge of the database - thats what the sys admin is for. Whereas sys admin may not need the same exact skills … |
| | It doesn't look like you are considering the last name when sorting. If the names are already sorted by last name you should only be sorting the first names where the last names match. For example if you have the names Phil Doe, Jane Doe, Fred Doe, Bill Doe, Jane …  |

| | Hi, I have heard of source forge and github and the like but I was wondering if anyone knew of a site that listed open source projects looking for members - so definitely WIP instead of a released project. I actually found just such site about 2 months ago, after … |
| | I think the question would be stronger if you defined it better. Data? What data? At its most basic level yes data is important but only when used by skilled people. Data left sitting on a hard drive is useless, as is data that is used incorrectly. Human resources, along … |
 | Re: Error with linq Well, I'm not sure what you expect us to do. We don't have access to the files and you haven't posted up any code. The first error is quite specific however - open the file and find the validation errors. |

| | There is a number of books on game programming for IOS (objective C) and Android devices. I know you want to use your VB.Net knowledge but those devices are probably going to be the mobile game platforms of the future.  |
| | Hi, What database to use depends on how much data you expect to store (although that is also not that important unless the amount of data is expected to be HUGE). You could save your data in text or XML if you wanted but there would be a reasonable performance … |
| | Oddly enough you have the correct the code to make the lblWarning not visible, yet for the list you have coded lstCity.Visible = Not lstCity.Visible. try: [code] lstCity.Visible = false [/code] You never seem to sent toZone, only fromZone, so your check to see if they match can never match. … |
| | I'm not sure why you listed all that code. The part relevant to your SQL operation would have been adequate. I gave up looking for it so I don't know for certain the answer to your question but I would assume you are trying to insert a value into a … |
| | Your question is a bit hard to understand. if you are looking for a .Net control that can be used to display the records from a database on a webpage you can use a dataGridView or a Repeater control. Is the problem with your control or your data request to … |

| | Re: List View In the listbox.selectedindexchanged() method select which item was selected with the items.selecteditem method and use that to populate the url for the image. If the item text isn't the image URL ( which is probably the case) store the URL in the value parameter of each list item and use … |

| | You only set your bool value to false If Convert.ToString(objSheet.Cells(excelRow, 1).value) == "" and never at any other point. In other words your loop runs and runs and runs if that bool is not false (which it won't ever be if it isn't the first time). you end up running … |
| | I think that is because all you are doing is subtracting 32 of KeyAscii. You're not doing anything with KeyAscii after that, remember it is just a variable you defined. You actually need to take that converted character and append it to the characters in the text box. Rather, if … |

| | Re: to the power In text the power sign is normally given by the ^ character (above your 6 on the keyboard. E.g. 10^2 = 100. Using a word processor the 2 would generally be turned into superscript which places it above the other characters and smaller. In HTML you can use the <sup></sup> … |
| | Well,the error is saying it a nullException meaning your secondForm is empty or hasn't been loaded with anything. This is probably because you are trying to match it with elements on the page called "form2". Are you sure they exist on the target page? |
| | I can't actually see where you use the entered hours of labour. You use the constant version here: [code] SubTotalDecimal = PartsDecimal + HOURS_OF_LABOR_Decimal [/code] And later you have this: [code] ElseIf HOURS_OF_LABOR_Decimal > 0 Then [/code] The whole idea of a constant is just that - it never changes. … |
| | Re: Data Security If you don't secure the end points of the transmission (via SSL or something similar) then a man in the middle can always find a way to access the packets. Steganography is just encryption with another name. If you don't want people to be able to see the packets use … |
| | I've used hidden fields on the page to do this. Others may have a better way but this has worked OK for me before. Include a label as a hidden field on the page and write the variable into it using javascript. Your .Net code can then read from the … |

 | Are you referring to using CSS to style the location of the button? |
| | Not sure, out of interest I looked into but couldn't see anything. My advice would be not to. Its the online equivalent of a store attendant asking if they can help with anything. Very annoying and 99% of your users are going to make closing it the first thing they … |
