I'm using web cam to save,update the image in base directory folder.I can save the image but, while attempting to update the image..I caught an error!!
C#.Net:
The process cannot access the file 'C:..~..inDebugcustomer_photos10.jpg' because it is being used by another process.
On line 128 I'm attempting to delete an image file that was previously shown in an ItemsControl, but was removed by line 126. So the image is not being shown in the program at the time I'm wanting to delete the file.
Error:Additional information: The process cannot access the file 'c:StudioExit PopupKeith Sketch.png' because it is being used by another process.

How can I pass ":" or " " as an argument to a process?
I start a process which takes an IP and port number (ex 222.240.224.131:80) as argument. Another character that I want to pass is white space character. Both of these characters cuts the argument string and sends only the part that leads them.

View 2 Replies View RelatedI am having a problem with deleting gridview rows. I am populating my gridview by selecting value in a dropdownlist then by clicking the add button, value will be added in my gridview, here is my code:
In my aspx:
<asp:GridView ID="GridView1" runat="server"
CssClass="mGrid" EmptyDataText = "There are no records to display">
<Columns>
<asp:TemplateField ItemStyle-Width="10">
<HeaderTemplate>
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server"/>
[Code] ....
With the btnRemove codes above, If I clicked it, it'll remove all values in my gridview even the unchecked rows, what I want is that just the checked rows not all. And are there any other simple way of removing rows in a gridview than using checkbox? I am using c# with asp.net.
So I have this program which read single text file and write in other. Basically read every line then write to another file "this number is n times here + numbers".
How to modify this to store only 1 time the number in second file. What I mean is not like now:
Now output is:
Count of matching numbers in this group: 7
Numbers:
01070400
01070400
01070400
01070400
01070400
01070400
01070400
Is better to be:
Count of matching numbers in this group: 7
Number:
01070400
Code that I use is:
string path = "text.txt";
var result = (File.ReadLines(path)).OrderBy(x => x).GroupBy(x => x);
using (var writer = new StreamWriter("test1.txt")) {
foreach (var item in result) {
string outGrp = String.Format("Count of matching numbers in this group: {0}", item.Count());

View 4 Replies View RelatedI am facing the problem of adding the image in MS Access Database. I know that OLE Object datatype is used to insert the image in MS Access database.
I have already converted the image in Byte form but unable to add that Byte [] to OLE data type.
Is Byte compatible with OLE Object Datatype?
What i'm trying to do is load an image from my database create some graphics to it. probably just some lines and marks and save it back to my database. here's so far what I got.
for creating graphics:
} private void pictureBox3_MouseDown(object sender, MouseEventArgs e) {
draw = true;
} private void pictureBox3_MouseMove(object sender, MouseEventArgs e) {
if (draw) {
Graphics g = Graphics.FromImage(pictureBox3.Image);
[Code] ....
but the saving part doesnt work :( I think it only saves the image loaded to the picturebox but not the graphics created to it. how to merge it? i've tried to google it and found some sort of same cases but fails to make it work, something like converting it to bitmap.
Is it possible to save web page as image with web application? if yes then how?.I searched and searched and searched but all examples i found were for windows application and i'm facing lot of trouble while converting it for web application.

I have a .png file that my console app reads and puts into a structure that is saved as a file. The png is always the same so I thought I could just add it as a resource image to a resource file so it would be included in my program and not as a separate file. When I did that, the png shows up as a "SystemDrawingBitmap". If I examine this resource in a watch I see "Base" and "Static" members. Expanding those properties does not give me anything useful such as a pointer to the raw png data and its length in bytes.
If worse comes to worse, I can always make a hex dump of the png contents and then put the hex code into a CS file using static initialization.
Surely there is some way I can access the raw data internally and read the bytes into a byte array using C#

I am currently taking a C# class. Our current assignment has us entering a player name, and number of hits and displaying these in one set of labels. I have coded everything for the primary function of this program and it works. However, I also have to have a second set of labels that show the highest number of hits entered (if I enter 44, the first and second labels change to 44; if I then enter 27, the first label changes to 27 and the second stays at 44; and if i enter 55, the first label changes to 55 and the second label changes to 55) and the corresponding player name. I have tried searching and reading and I can't seem to figure out how this is done.
View 5 Replies View RelatedI have a question about memory allocation.I have a function that calls a lot of object constructors, which in return these constructors will allocate a lot of memory.Now, in my program I am sure that if I first call this function , say it will call the constructor of 100 object.If I call this function again and again, I am sure that it will only call the constructor 100 times again, and thus I am sure that the memory allocated in the first call can be reused again.
How can I reuse the memory allocated in the first call?Can I use something like boost:object_pool so that I can tell the pool to restart from the begining and do not allocate extra memory, just use what you already have?

I have to manage a Clinic. I need to delete a booking (for example, if John said he's coming on March 22nd at 15:30 but then he say he's not going to come, I have to delete that booking so another person can use it).
idSearched: the id of the person that is not going to come. I have a lot of specialties and each one has a list. So I ask for the speciality to delete the node (the node contains John's booking). If I don't find it, I return (-1). searchSpecByID return a pointer to the list where the speciality is. So head will point to the first node of the list. In nodeToDelete I have the node I want to delete.
The program detects OK when is the first in the list and when not, but it doesn't delete the node.
Code:
typedef struct bookingList{
tSpecialty specialty;
struct nodo* intro;
} tList;

Im trying to compare the image of a button to another image in Visual Studio like so...
//variables
Image active = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\active.png");
Image stunned = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\stunned.png");
[Code]...
btnStatusPlr1.Image SHOULD come back as True.Then I realized it might not be the same as setting the buttons image in the properties (Which is what i did to get the original image (the one being compared to))
I do have a feeling ive done something wrong here (Yes im a noob /> )
Variable active, is the same image as the buttons default (Well should be)
Basically, the task is to replace tabs with spaces, ensuring that the number of spaces is appropriate to get you to the next tab stop (i.e. if you were only 4 spaces away from a tab stop, don't replace the tab with 8 spaces).i've seen have included character arrays, and many have included multiple functions. I realize the text says "these exercises suggest programs of somewhat greater complexity than the ones earlie in this chapter," but it seemed like a very straightfortward task.Have i oversimplified or something?
Code:
#include <stdio.h>
#define TAB_STOP 8
int main()

int c, i;
