I am looking for a way to set the minimum ClientSize of a form. I'm new to c# and I am unsure of the best way to do this.

问题 I'm currently battling with Angular form array. I have a form in which I add the fields dynamically. I have created the form object: this.otherDataForm = this.fb.group({ }); I add the dynamic fields like this: addField(field: CustomFormField): void { this.otherDataForm.addControl(id_campo, new FormControl('', Validators.required)); } I loop through those fields: <form *ngIf="selectedProfile" [formGroup]="otherDataForm"> <div class="mb-3" *ngFor="let field of fields; let i = index"> <label>{

But when I try to detect individual boxes in the group of boxes, I am not able to do so and the opencv returns only one contour for all the boxes. The file referred in the for loop is a file containing coordinates of the bounding box. The cropped_img is the image

问题 I have two view functions in my views.py. The first one renders the index.html Second is created for the form action on index.html (update_db). When I click on submit on the index.html file, it changes url to /update1, but the function call has print('HI') and I cannot see that on console. Neither are any new files created after it runs.
