how I could use a Image control where I can upload an image to a folder(done that) and then take that image right after uploading it (in the same line of code) view it on the image control...
View 5 RepliesSo I am upgrading the system from 3.5 .NET to 4.5.1 and fixing any bug that I could find. Long story short, I run into an issue that basically tell me it couldn't find the images in the resource file. I figured out a work around, but first I have to set the picture box or background Image in design time to none. I ran into this Properties Windows while changing the value of picturebox for my user control saying: Property value is not valid. Object reference not set to an instance of an object. This usercontrol is taken from another user control from a different project. Basically, we are reusing it.

View 1 Replies View RelatedI've been looking for a C# library that is well documented and can show DICOM (medical CT scan data, including the image) as jpeg/bmp data that is viewable in a PictureBox.
I've only found OpenDicom which is more or less unsupported now and EvilDicom - whose owner has made some significant changes to it, making all existing stack overflow questions on it irrelevant.
Background: I've created a projected and added a mdf database file to it.
I am attempting to fill my datagridview with data from a table that I've added to my mdf file.
I am having a hell of a time figuring out the correct connection string and datasource file path for it.
I've decided on using OleDB because that's what I am most familiar with.
I clearly see the rule "Don't tell us to give you code!" but I cannot find a good tutorial from START to FINISH on how to do what I am trying to do.
As stated, I think my connection string is wrong. Even if I change it to
OleDB (string conStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Database.mdf"
I get a new error saying it cannot recognize the database format.
public partial class DataViewer : Form {
string conStr = "Provider=SQLOLEDB;Data Source=Database.mdf";
DataSet dS = new DataSet();
DataSet tdS = new DataSet();
OleDbConnection con = null;

I have an application that Opens files with different extensions for viewing purposes only. I use MFC with Multi-Document template.
When I go to Windows Explorer in Windows 7 and right-click on Libraries - Documents, and scroll down to New, Explorer shows multiple links for creating new files with these different extensions.
My application does not create New documents. It just opens them for viewing purposes. In fact, I have disabled the New portion of the mainframe window.
My code includes:
EnableShellOpen();
RegisterShellFileTypes(TRUE);
I am at a loss as to what portion of my code would have placed these links into Windows Explorer!
Is there any way to prevent them from being created in the first place?
I have researched quite extensively, experimented, and still cannot seem to change the properties of a control on an active winform from a user control.
So I have a user control which populates each dynamically added tab page in a tab control.
I have a textbox in the user control which I would like to type in, capture the text_change event, and change the text of the label in the winform.
How do I bind a DATE column in a DataGridView Control to a DatePicker control (using C#)? I already have the DataGridView control bound to a database stored procedure which takes a DATE value as a parameter and selects joining table based on the results.

//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)
i've taken a couple courses in C Programming and all of the assignments were pretty basic. I've been looking into some of the awesome things that people have been doing with the Raspberry Pi and noticed that some of them are using the C language to control robotic arms and LEDs. I skim the code for some of these projects and notice they are using header files and code that i have never seen, nor are they in the books that i have. for example:
#include <fcntl.h>
#include <sys/mman.h>

is there a way to tell WPF that I'm going to do a lengthy update on a control (TextBlock), and that it shouldn't redraw it until I tell it I'm done? I'm adding a large number of items to the Inlines property, and it has to redraw the entire control every time I add an item, which takes a very long time - about 1 second for every 100 items. I know some other frameworks allow freezing of certain controls, but I haven't been able to find anything in the documentation or on google. I've tried collapsing the TextBlock, and then making it visible again after the update, but it did not improve the performance at all.

I am running some simulation, in which i need to control the iterator of a multimap, like
multimap<double, int> mapp;

int n=6;
for(int i=0; i<5; i++) {
for(auto it = mapp.begin()+i*n; it!=mapp.begin()+(i+1)*n; it++) {

However this way of controlling is not possible for multimap. Why and how the make it work? Do I need to overload the operator +?
is there any way to have the program control go some two paths at once? For example: if my program has two functions, one that does some simple calculation that requires nothing from outside it to set the variables and another that displays text for the user to read then enter something. Is there any way to have both run at the same time?
simpleFnc()
{int a = 1;
int b = 2 ;
int c = a+b ;
[code]....
There is no connection of simplefnc to anywhere else in the program so is there any way to get it to run at the same time the other function is running?

I am having trouble understanding what I need to do to halt the flow of a program until a video file finishes playing. So far I have accomplished getting the video to play, but the program continues while the video is playing rendering the content of the program on top of the video making it not seen.
My goal is to make the video play, then once it has finished the rest of the program should run.
So far I have this in the start up area of my code:
//Initialize components for DirectShow to stream a video at start-up
CoInitialize(NULL);
//creates filter graph manager
[Code].....
After this code runs once, the program proceeds immediately into the loop where my update and render functions for the program runs. Preferably, I want to stop just the render function while allowing the update to continue to check if the user presses a key to skip the video. What do I need to add to the code to do this?
I'd like to make a control panel for different social media to control multiple account and have proxy support. I think i need to learn multithreading and socket programming right ?
