Preferred Size Values For Forms While Taking Borders Into Account?
Jun 14, 2011
I'm modifying an existing form in Visual Basic 2010 Express and attempting to work out some small kinks I've noticed. The one that I'm having an issue with is getting the form to completely fill the screen without the border going off screen. When I set the form's Size values at W:1024,H:768 the page always opens a little off. I tried setting the size a little smaller, W:1020,H:764, and it still does not perfectly fill the screen. Does the Size value include the border pixels or are the border pixels added to the form's Size value? Is there another value somewhere that could be affecting this?
I have this fingerprint scanner I'm working with. The fingerprints taken are index/stored in our imaging system and the fingerprints are put on certain documents and printed.When I scan the image in and then load it into a bitmap object, the width and height are (w:480,h:640).Now if I open this file in any image viewer and print it from there the finger print is as big as a fingerprint should be.Now when working with it in code, it's huge. I have found some resize code online, but the resulting image is horrible.Is there anyway to resize an image while taking in account the dpi and such so the image is highest quality (same as print out?).
I have a MDI container form with menustrip, toolstrip and statusstrip on it. The backcolor of these items is black. The toolstrip and statusstrip show ugly white borders around them which I want to get rid of but there seems to be no such property like bordercolor or anything where I could change them.
I have a lot of forms that get placed in specific locations at run time. I need to disable relocating these forms, but I would like to keep the borders and titlebar.
I have tried jmc's codebank submission called "immobilise" but did not work for me, forms were still draggable (could be my mis_use, but no errors were thrown)If this isn't doable, is there a way to hide only the titlebar, but maintain the 3D blue borders all around?
I have now a Drawing Custom Borders, Download by CodeProject and now i'm being use, but my problem is how can i apply with my changes of my customize borders...i've been changing in Runtime not in editor...
I have looked all over the web for a way to set up a VB 2008 combobox but what I have seen makes me shudder! I want to , as In Access VBA, set the recordsource/datasource for the combobox i.e. the list shown in the combobox, to the values of another table (currency) and then when the user selects one of these values to store it in the (already) bound field of the combobox (to another table). In Access of course there was a wizard for this sort of thing, but in VB 2008 looks like it is just lots of code.
I want to take the values from textboxes on a windows form and then update the values in the sql server database...I want to update only those fields for which a value has been entered by the user and leave the database fields as it is (no change or updation) for which the textboxes are left empty by the user.....I opted for sql command and then i couldn't find out How can I generate the query dynamically for such a situation??? Like I intialize the string by str= " Update Bookings set " and then how i can alter it by considering the textbox values that have been changed....I couldn't find the way...I need shortest and optimized code for this situation....
I would like to draw a figure like this. But i do not know how to start drawing it. What i could do is simple mathematics calculation, display something in a label and taking some values from a textbox.

Edit:
I haven't yet coded for the update option...Here is my insertion code and i wanted to implement the update feature the same way just couldn't figure out how i can generate the query dynamically....It's a Booking System application
Currently I am trying to receive input from a user for up to five usernames and passwords. I can not figure out the best way to do so. I have tried textboxes but that makes forms look dirty and redundant.[code]...
If I have form say sized 1300 x 800, I would like to proportionally size the form to the computers screen size. I can get it to size to the screen size, but it is not proportional
I am after a property that makes a control (textbox, datagrid or other) move according to the forms size. Because some of the controls I got does that, and I really don't want it. I've been looking at them but could not find it
I've just finished creating a basic login system which enables you to create an account and select either a "Student" or "Teacher" account.
Once the account is created it's stored in an Access 2007 database. The field the account type gets stored in is called AccountType. When users log in with their unique username and password I want the program to take them to a different form depending on whether they have a student or teacher account.
How can we add a list to a combo box from a txt or excel file when entering an account number. the details must only be displayed for each defferent acount information. for example. account no 3332 must show a name and telephone number in to separate comboboxes. although it must contain lets say 4 telephone numbers and 4 names that are located in a text document.
Does anyone know how to run windows explorer with an admin account while logged in with a non admnistrative account? i want to be able to open up an admin share on a remote host with windows explorer instead of iexplorer. I tried some code I found on the net to impersonate but it didn't work.
I have a login form that consists of 2 text boxes: txtUser, txtPass. Now these are not bound to any data table & I don't what them to be bound. When a new user enters his user name & password, I want to add these on a data table that has two columns: User, Pass. Data table information: Data Source = Login.accdb, Data table = LoginTable, Connection = LoginCn. I use visual basic 2010. So how do I do this?
I am currently working on a stock market monitoring application. how to create a new portfolio(sort of a personal account) for each user that accesses the system such that 2 different users do not have the same portfolio. I am making use of SQL server for my database.
I need to be able to start with Form1, move to LoginForm, then back to Form1 taking 2 variables and the "values" they have in the LoginForm back to Form1 and using the variables. I start with the main form (Form1) and have the user enter some information. Once they click OK I have the LoginForm open. After they enter their credentials I will check to make sure they are legal users, then go back to Form1 (here is where I need to take the Username and Password with me) to log onto a server using the same credentails from the login form.
I have an ASP DataGrid and I'm applying sorting to it. Well, as I was looking at an example, they had a function similar in function, different in name, to[code]...
We have a windows service running under a network account that calls and runs an ActiveX exe. The exe is running under the local system account, not the network account of the service.
This is newbie VB question. My son is learning VB and I am learning with him. We have RichEdit control application (non WPF), where we input text, formatting its Style (bold, italic, underline, etc.). Our next task is to save the text together with its attributes into the file. The question is: what type of serialization is preferred at this case?
I have 4 rounding options: None, Standard, Up, Down If they choose None and the number is 108.7879, I just want to display 108.78 with no rounding. I know I probably can use Math.Ceil for Up and Math.Floor for Down, but I am not sure what to use for None or Standard.
I am working with Vb.net 2005. I have used Crystal reports in some forms. The Crystal Report on the other hand use parameter field, therefore when you run the application an "enter parameter dialogue box" is loaded.
I have adopted a technique where I pass existing objects to forms so that they can display the object's content and allow the user to alter it if necessary. The form is not bound to the object, so when it comes time to act, the form sweeps up the content of its controls and puts them into the object. The object is then validated and any issues reported to the user. If the object is valid, it may be handed back to the caller so the caller can refresh a view/list/etc.
So far, so good. However, if the form's content, or lack of, creates an invalid object and the user does not correct it, maybe cancelling the form, there's a chance the form will hand an invalid object back to the caller. This is not good.
Essentially I'm looking for an elegant and efficient way of either leaving the object as it was or rolling back if the user cancels the form/action.
I have considered a range of techniques, each with many pros and cons. I'm keen to consider some other views.
I'm looking for a method of generating unique identifiers for a record class being created locally and then persisted in various formats (XML, SQL, etc.) I've seen people using DateTime and GetHashCode, but that seems to lend itself to duplicate identifiers depending upon the sample size. GUID is a bit overkill, as I don't need anything that unique (large) at the global level. I'm also aware of using GUIDs and GetHashCode to get the size down a bit, but duplicates tend to crop up here as well. Any best practice or method for generating simple unique identifiers?
I have a situation in which I must execute a dynamically built stored procedure against tables that may, or may not be in the database. The data retrieved is then shunted to a VB.Net backed ASP based report page. By design, if the tables are not present in the database, the relevant data is automatically hidden on the report page. Currently, I'm doing this by checking for the inevitable error, and hiding the div in the catch block. A bit kludgy, but it worked.I can't include the VB code-behind, but the relevant stored procedure is included below.However, a problem with this method was recently brought to my attention when, for no apparent reason, the div was being hidden even though the proper data was available. As it turned out, the user trying to select the table in the dynamic SQL call didn't have the proper select permissions, an easy enough fix once I could track it down.First and foremost - is there a better way to check for a missing table than through catching the error in the VB.Net codebehind? All things considered, I'd rather save the error checking for an actual error. Secondly, is there a preferred method to squirrel out a particular OLE DB error out of the general object caught by the try->catch block other than just checking the actual stack trace string?
SQL Query - The main gist of the code is that, due to the design of the database, I have to determine the name of the actual table being targeted manually. The database records jobs in a single table, but each job also gets its own table for processing data on the items processed in that job, and it's data from those tables I have to retrieve. Absolutely nothing I can do about this setup, unfortunately. [code]
