Im creating an application to create rich text documents. As a part of of I have to add a text input field that can produce MS Word like features so that I can do word processing on the writing text.
At the moment VS studio provides, only Rich Text Box . But it doesnt provide that kind of features of the word processor.
Is it possible to add a word processor control to the Form if possible how can I do it? (I need to do this using the features of VS 2008 TS)
I'm creating a simple word processor for class but I'm having some trouble on the close button. The Close button is supposed to close the file that the user is working on but not the word processor itself. How would I go about closing the document that the user is working on?
Here is what I have so far: Private Sub CloseToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CloseToolStripMenuItem.Click Dim intfile As Object rtbDocument.Text = "" FileClose(intfile) End Sub
This gives me an error message "Option Strict On disallows implicit conversions from 'Object' to 'Integer'." When I'm not using Option Strict On the code seems to work but VS gives me a warning message, "Variable 'intfile' is used before it has been assigned a value. A null reference exception could result at runtime. I'm not sure what value to assign the 'intfile' Object.
I need to add cut, copy, and paste functionality to my word processor. I'm using Visual Studio 2010 and we have no textbook this semester. I know they're in that tool box somewhere!
Public Class wordProcessorForm Dim mblnDirty As Boolean Private Sub wordProcessorForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load [Code] .....
I am doing word processor but I cannot do the font it is not select fonting text in textbox what shall I do? Font code= fontdailog.showdailog fontdailog.font=textbox.font textbox.font=fontdailog.font In this case it can not do select text to format 2. In word processor how do insert many page?
i'm making a small word processor program using vb 2008 and i need the codes for the following commands: creating table adding and removing rows and columns header and footer
How can I add controls to a form in code and set the properties of the controls using the With statement?Also I would like to know how to add a container control and then add a control to that container.
I have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.
I have a module level sub that I use to clear text fields etc on my forms:
CODE:
The problem I have is in the last few lines of code as I'm not really sure how to access the text boxes contained within the tab controls (of which there are many tabs and many text boxes).
This is the closest I've got but I am getting an "option strict on disallows late binding" error on the tabCtl in the following line.
i have 1 old and 1 new pc and i want to use old pcs processor :D (it need for my experiments :icon_evil: lol just joking ) i know i dont need this pcs power but i dont want to junk my other pc is there any way to do it.i just need how can i connect them?i ll write a library for other pcs and i give a order to use bla bla functions and i want it says return information to my new pc. i know we have network delay. but for example network rendering its accelerates the process too much.i want working in partnership this two pcs for my programs?
I am looking at developing a pre-processor and wanted to know how to configure IIS to pass the requesting page to it before it is returned. For example, the user would navigate to a page with a ".app" extension and IIS would send the file to a console program I wrote to be interpreted, before sending the page back to the user.
I am currently doing the project using vb.net which require me to find the proccesor speed and memory of ram....now i am searching the code from internet ....so currently, i havnt done anything.....i think i should use WMI or windows API to get those Info ....
I have a form. And some controls(such as TextBox,ComboBox,etc.) on the form.Now,I want to store the controls' Text into a .txt file(or any other formarts).Then I want to read the text in the .txt file to my controls.
I developed my application using vs2008 on a 32bit XP machine using ms access. My new machine is Vista 64bit using vs2008. Ms access has stopped working. It is looking for a 64bit software. Is there any? how do I work around this? will this hurt me when deploying to non 64bit machines?
how to determine this? I know how to get the "processor ID" etc. but this is apparently not a unique identifier.This is for an intel i7 975. My boss has asked us to make sure that no-one tampers with several parts of a process control computer.
I was wondering is it possible to search the registry for a string containing "shutdown" but as a proccess wich takes about 20% processor power instead of the 50% i cant quite afford. Its a nasty joke going around school atm to stick a shutdown command on computer startup, was gonna see if i could do something about it.
I have a multi-processing application that kicks off up to 4 threads at a time to process data into a SQL-Server database. It seems to work okay, except at times the processors are pegged at 100% and all threads slow down a bit.
So, what I want to do is conditionally fire a thread based upon the processor load... if they're already running at 100%, it makes no sense to kick off another thread.
Is there a way to determine what the processor load is? Task manager shows processor load, so there probably is... but how do I do it?
I get this warning message when I run my project. Can someone explain to me what this means and how I can remove it, or if I need to worry about it. [code]
Inside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.
I'm working on a project which will entail multiple devices, each with an embedded (ARM) processor, communicating. One development approach which I have found useful in the past with projects that only entailed a single embedded processor was develop the code using Visual Studio, divided into three portions:[code]Feeding the embedded compiler/linker the code from parts 1 and 3 yields a hex file that can run on the target system. Running parts 1 and 2 together yields code which can run on the PC, with the benefit of better debugging tools and more precise control over I/O behavior (e.g. I can make the simulation code introduce certain types of random hiccups more easily than I can induce controlled hiccups on real hardware). Target code is written in C, but the simulation environment uses C++ so as to simulate I/O registers. For example, I have a PortArray data structure; the header file for the embedded compiler includes a line like unsigned char LATA @ 0xF89; and my header file for simulation includes #define LATA _IOBIT(f89,1) which in turn invokes a macro that accesses a suitable property of an I/O object, so a statement like LATA |= 4; will read the simulated latch, "or" the read value with 4, and write the new value. To make this work, the target code has to compile under C++ as well as under C, but this mostly isn't a problem. The biggest annoyance is probably with enum types (which behave as integers in C, but have to be coaxed to do so in C++).
Previously, I've used two approaches to making the simulation interactive:Compile and link a DLL with target-application and simulation code, and have VB code in the same project which interacts with it.Compile the target-application code and some simulation code to an EXE with instance of Visual Studio, and use a second instance of Visual Studio for the simulation-UI. Have the two programs communicate via TCP, so nearly all "real" I/O logic is in the simulation program. For example, the aforementioned `LATA |= 4;` would send a "read port 0xF89" command to the TCP port, get the response, process the received value, and send a "write port 0xF89" command with the result.I've found the latter approach to run a tiny bit slower than the former in some cases, but it seems much more convenient for debugging, since I can suspend execution of the unmanaged simulation code while the simulation UI remains responsive. Indeed, for simulating a single target device at a time, I think the latter approach works extremely well. My question is how I should best go about simulating a plurality of target devices (e.g. 16 of them).The difficulty I have is figuring out how to make each simulated instance get its own set of global variables. If I were to compile to an EXE and run one instance of the EXE for each simulated target device, that would work, but I don't know any practical way to maintain debugger support while doing that. Another approach would be to arrange the target code so that everything would compile as one module joined together via #include. For simulation purposes, everything could then be wrapped into a single C++ class, with global variables turning into class-instance variables. That would be a bit more object-oriented, but I really don't like the idea of forcing all the application code to live in one compiled and linked module.What would perhaps be ideal would be if the code could load multiple instances of the DLL, each with its own set of global variables. I have no idea how to do that, however, nor do I know how to make things interact with the debugger. I don't think it's really necessary that all simulated target devices actually execute code simultaneously; it would be perfectly acceptable for simulation instances to use cooperative multitasking. If there were some way of finding out what range of memory holds the global variables, it might be possible to have the 'task-switch' method swap out all of the global variables used by the previously-running instance and swap in the contents applicable to the instance being switched in. Although I'd know how to do that in an embedded context, though, I'd have no idea how to do that on the PC.
Is there any nicer way to allow simulation logic to be paused and examined in VS2010 debugger, while keeping a responsive UI for the simulator front-end, than running the simulator front end and the simulator logic in separate instances of VS2010, if the simulation logic must be written in C and the simulation front end in managed code? For example, is there a way to tell the debugger that when a breakpoint is hit, some or all other threads should be allowed to keep running while the thread that had hit the breakpoint sits paused?If the bulk of the simulation logic must be source-code compatible with an embedded system written in C (so that the same source files can be compiled and run for simulation purposes under VS2010, and then compiled by the embedded-systems compiler for use in real hardware), is there any way to have the VS2010 debugger interact with multiple simulated instances of the embedded device? Assume performance is not likely to be an issue, but the number of instances will be large enough that creating a separate project for each instance would be likely be annoying in the absence of any way to automate the process. I can think of three somewhat-workable approaches, but don't know how to make any of them work really nicely. There's also an approach which would be better if it's possible, but I don't know how to make it work.Wrap all the simulation code within a single C++ class, such that what would be global variables in the target system become class members. I'm leaning toward this approach, but it would seem to require everything to be compiled as a single module, which would annoyingly affect the design of the target system code. Is there any nice way to have code access class instance members as though they were globals, without requiring all functions using such instances to be members of the same module?Compile a separate DLL for each simulated instance (so that e.g. if I want to run up to 16 instances, I would include 16 DLL's in the project, all sharing the same source files). This could work, but every change to the project configuration would have to be repeated 16 times.Compile the simulation logic to an EXE, and run an appropriate number of instances of that EXE. This could work, but I don't know of any convenient way to do things like set a breakpoint common to all instances. Is it possible to have multiple running instances of an EXE attached to a single debugger instance?Load multiple instances of a DLL in such a way that each instance gets its own global variables, while still being accessible in the debugger. This would be nicest if it were possible, but I don't know any way to do so.If I use one VS2010 instance for the front-end, and another for the simulation logic, is there any way to arrange things so that starting code in one will automatically launch the code in the other?
I'm simulating some threading in a Windows Service, and the Thread.Start routine for each of my threads points directly to the following:
Private WithEvents CheckForOrdersTimer As System.Threading.Timer Private Sub timerCheckForContracts_Tick(ByVal stateInfo As Object) ' Ticks every 5 seconds, then spawns threads until we're at our max Do
[code]....
the threads aren't even doing anything yet, but with more than two threads running at the same time, my processor (Core 2 Duo 2.4 w/ 4GB) gets pegged and Windows gets really sluggish. According to what I've read, Thread.Sleep shouldn't be consuming any resources at all while it waits, but it may as well be running in a tight timing loop.
EDIT: Per the requests, I've expanded the amount of code I'm using. I was initially doing some database work before spawning each thread, but I've removed it and the processor maximization still occurs with just the code here (and, of course, the OnStart method for the Windows Service.
I am calling a function from a VB.NET webserver to a custom written unmanaged DLL.If we call this DLL via a webservice on a multi-core server we run into problems and it always crashes.If I reboot the server and make it only use a single-core, it always runs fine and never crashes.I know the DLL call is responsible for the crash as I have outputted debugging code just before and after the DLL call.I can force the processor affinity of the .NET code to 1 core but this doesn't apply to the unmanaged DLL.How can I force the unmanaged DLL to only run on a single core as I am sure this will solve the problem?
