They changed the Recycle Bin icon? That's my favorite feature, and the only reason I use Windows! That's it, I'm officially and irreversably moving to Minix. This travesty cannot be be reconciled. Who does Microsoft think they are? Geez!

Um...what?

If the sample of the file you presented is accurate, then it's not a binary file, it's a variant of CSV. `fread` with that structure won't work since the file has to be parsed as a comma separated format. For it to work, the file would need to be created …

Is that a big square hole in your wall?

That code is definitely C#. Since the question did not ask about conversion to C, I've moved the thread to the C# forum so that the resident experts have a better chance of seeing and answering it.

`BindingSource` is your friend: private BindingSource _bs = new BindingSource(); ... // Initialize DGV _bs.DataSource = ds.Tables("Customer"); dataGridViewCustomers.DataSource = _bs; ... // Filter DGV _bs.Filter = string.Format("customerID LIKE '%{0}%'", customerID);

Your dequeue logic has two major problems: 1. It does not take into account updating the `bottom` node. 2. Wherever the node is deleted, the list is terminated with NULL rather than maintaining the structure if there are subsequent nodes. This is a basic single linked list deletion, so you …

That's by design. The editor isn't a mere text field, it's an actual text editor supporting Markdown where indentation is significant. If tab moved to the next page element, creating code blocks manually would be tedious at best.

Help yes, do work for you, no.

> What does it exactly mean to "escape" a string and where does the code for this go? Escaping a string means converting characters that would be treated as special in a query as literal characters. A good example is a single quote. This has special meaning in a query, …

The problem is that a naive `atoi` like conversion won't work directly with hexadecimal characters because you need to take into account that a-f represent 10-15. That too requires a minor conversion as well to get the values you need. Once you have those values, this formula works to build …

Alt+s works for me, no shift necessary. I'm also on Windows 8.1. What browser are you using?

Your `else` clause is missing braces. That only works when the body of the clause has one statement, yet here you have (presumably) three.

Creating controls at runtime is certainly possible. For example: using System; using System.Drawing; using System.Windows.Forms; namespace FormScratch { public class MainForm : Form { private Button buttonAddImage; private FlowLayoutPanel flowLayoutPanelThumbs; private void InitializeComponent() { buttonAddImage = new Button(); flowLayoutPanelThumbs = new FlowLayoutPanel(); SuspendLayout(); buttonAddImage.Location = new Point(13, 13); buttonAddImage.Name = …

A continuation would help in identifying a pattern. Presumably, it might look something like this: 1 1 2 2 3 2 3 4 3 4 5 3 4 5 6 4 5 6 7 4 5 6 7 8 4 5 6 7 3 4 5 6 3 4 5 …

Hmm. Of the top of my head, I'd say it really depends on what features you plan to support. If there's a huge amount of intersection between the two, I might choose to implement the vector as a composition/specialization of a matrix of 1xN or Nx1. Alternatively, a matrix may …

> i mean the output should be vertical direction Which means what, exactly? Show us an example, because right now each number is output on a separate line, and that looks a lot like 'vertical' to me.

Well, one thing that stands out immediately is C isn't so pretty that it allows commas in a large number. In fact, if you're exceptionally unlucky (which it seems you are), including them will be syntactically correct but semantically bonkers.

What have you done so far?

In the south it feels like spring time, it's January, I *like* the cold, and your name is chilly. I ban you for reminding me that I haven't properly had my winter yet this year. Taking bets on how many people will check to see if chilly is *actually* banned …

What do you need help with? What have you done? This is clearly homework, so we need some proof of effort before helping (as per Daniweb rules).

There are a few problems, and most of them stem from misunderstanding pointers. On line 12 you have this: while(i <= cnt) That's an off by one error. Arrays are 0-based in C, which means if the user enters 3, you're processing the indexes 0, 1, 2, *and* 3 rather …

What do you have so far?

All I see is a homework assignment, which violates our rules. Please show us your honest attempt and ask an actual question.

> the best monitor is what you like the best, at a price you can afford Much yes. I'm a fan of Acer LED monitors, personally.

The code looks dicey, especially how you incorrectly delete `cobj` in the first code. What are you really trying to accomplish with this? The class and variable names aren't enlightening as to the underlying design problem you want to solve here.

You've mostly got it: #include <stdio.h> int main(void) { int k = 80; void *p = &k; printf("%p\n", p); // Move forward one byte p = (char*)p + 1; printf("%p\n", p); return 0; } The result of a cast isn't a suitable lvalue, so you cannot use the `++` operator. …

Nesting functions is not supported in C++.

The two primary problems are that head is never updated in `main`, and your output loop never sets `stdPtr` to `stdPtr->next`. Given your description of the problem, as well as syntax errors, I find it difficult to believe that the provided code is the same code that you're executing.

`stdout` and `stdin` are not tied, so the output from `printf` is only guaranteed to be flushed if you print a newline or call `fflush`. In this case, you probably don't want to print a newline, so the only solution is `fflush`: int main () { int i; printf ("Enter …

Agreed with Moschops, but this is still a legitimate question. > When does it become necessary to allocate memory for an array? Typically when the size of the array is unknown until runtime, or the lifetime of an array would be insufficient for your needs (such as returning a locally …

This is your homework, not ours. We'll help if you have a specific question, as long as the specific question does not constitute "do it for me".

> How later on reset all elements back to 0.0? There are a number of ways. One that comes to mind is: v2d.assign(2, vector<double>(3)); This will completely replace the contents of the vectors with default initialized objects. However, that can be troublesome if you have pointers into the original objects. …

Good luck and have fun! :)

Write code. Lots and lots of code.

It's a compiler optimization. Given that string literals are read-only, there's no reason to create two separate instances of the same string literal in memory.

Functions support parameters, which are designed for this exact purpose: int add(int a, int b) { return a + b; } int main(void) { int a = 5; int b = 2; int c = add(a, b); printf("%d + %d = %d\n", a, b, c); return 0; } This is …

That design sounds dicey to me. My preference would be for the main form to manage itself completely, where temporary dialog forms are opened as needed and pass back information objects through properties or events for the main form to own and manage beyond the lifetime of the dialog. For …

If you show us your code, we can offer advice on improving it. For now, I can only answer your questions. > Does fscanf not work with negatives? It works fine, provided you use a signed format specifier like `"%d"`. > Do I have to read in the entire file, …

Please read our [rules](https://www.daniweb.com/community/rules) concerning homework. I'll give you time to ask a more specific question and show your work thus far. Otherwise this thread will be closed as a rule violation.
